EMART EM-7W-LTL, two spotlights, 600 lm each review

Two spotlights that publish lumens where this shelf asks for lux — and gels instead of a dimmer.

What it comes to Two table-top spotlights built for exactly one job and open about it: aiming into a light tent or across a bench, with 180-degree heads, six gels and stands that fold into the lamp bases. The pair is the point — two directions on a small subject. What this page does not give is any of the three figures the shelf compares on: lumens instead of lux with no beam angle, CRI 90+ at the bottom of the shelf, and no dimming at all.

What the maker commits to in print

Two high-output table-top photography LED lights with stands, 12 LEDs each, 600 lumens, CRI 90+
“The lamp head swivels up and down 180 degrees, so you can adjust your macro lighting light beam to the perfect angle”
“The retractable bracket which has new spring design can neatly be folded away into the base of the circle spot light itself”
5,500 K, with two color gel filters stated to change the kelvin temperature for cooler or warmer photos — two white, two orange and two blue supplied
“Fit most of table top studio photo shooting tent light cube diffusion softbox”
Eighteen months of after-sales quality assurance

NO lux. NO beam angle. NO dimming. NO battery or supply described. Nothing about flicker.

Six hundred lumens, where this shelf asks for lux

Lumens are what LEAVES the lamp. Lux is what ARRIVES on the subject.

A 600-lumen source in a narrow beam can put more lux on a small area than a 2,000-lumen panel spread across a wall. The same 600 lumens spread wide puts down very little.

Converting between them needs the beam angle, and this page does not publish one.

So the figure cannot be set against the ULANZI VL49 RGB’s 800 lux at 0.5 m (1.6 ft) or the NEEWER SL90C’s 1,090 at 0.5 m (1.6 ft).

“The distance is part of the measurement.”

Gels instead of a bi-color mix

Five thousand five hundred kelvin, fixed, with two white, two orange and two blue filters.

A bi-color panel fades between warm and cool emitters: changing the temperature costs a little output at the extremes.

A gel SUBTRACTS. An orange filter blocks the blue end to make the light warmer, and blocks it to the tune of a stop or more.

Six gels give a warm, a neutral and a cool setting per light, paid for in brightness. On a bench at thirty centimeters, where there is light to spare, that is a fair trade.

And no dimmer at all

The only light on this shelf with no dimming published — no range, no steps, no mention.

So the controls are: move it, gel it, or switch one of the pair off.

Thirty centimeters to forty-five halves the light on the subject, which is the most precise control available here.

For product work on a bench, workable. For balancing against a window, not.

A stand that folds into the lamp

“The retractable bracket … can neatly be folded away into the base of the circle spot light itself for quicker and more convenient storage.”

Which is a small, genuinely good idea for something that lives in a drawer between uses: nothing to lose, nothing to assemble.

And a head that swivels 180 degrees up and down — which is what lets a tabletop spot be aimed DOWN into a light tent.

It says what it is for

“Fit most of table top studio photo shooting tent light cube diffusion softbox.”

This pair is not a key light for a face. It is the light you put outside a diffusion box — and the NEEWER 60 cm (23.6 in) cube and the published PYXEL tent on the light-tents shelf of this site are built to be lit from exactly here.

Specifications

Output in lux with its distance	600 LUMENS PER LIGHT — and lumens are not lux. Lumens measure the total light LEAVING a fixture; lux measures how much ARRIVES on a surface, which is why this shelf's introduction asks for lux with a distance. The two cannot be converted without knowing the beam angle, and no beam angle is published here. Six hundred lumens from a 12-LED spotlight is a narrow, concentrated beam rather than a panel wash, so the lux at half a meter could be high and the coverage small. This and the published ULANZI K20 are the two pages on this shelf that publish a flux instead of an illuminance
Color temperature range	5500 K, FIXED, described as a "perfect daylight temperature" — and then the mechanism that moves it: TWO WHITE, TWO ORANGE and TWO BLUE GEL FILTERS, two color gel filters, stated to change the kelvin temperature for cooler or warmer photos. That is color temperature by subtraction rather than by mixing: an orange gel in front of a 5,500 K source makes it warmer and dimmer, where a bi-color panel fades between emitters and loses nothing. The ULANZI VL49 on this shelf is the only other fixed-temperature light here, and it has no gels
Accuracy indices	CRI 90+, stated — the JOINT WEAKEST index on this shelf with the Torjim pair and the ULANZI K20, behind the 95 of five lights, the 96, the three at 97 and the 98 above them. On a spotlight intended for tabletop product work the index matters as much as on a portrait light: a 90-CRI source renders a red product slightly brown, and a product photograph that needs its color corrected is a product photograph that will be returned
Dimming	NOT PUBLISHED AT ALL — no range, no steps, no mention. This is the ONLY light on this shelf with no dimming described, which on a 600-lumen spotlight means the only ways to reduce it are distance, a gel and switching one of the pair off. This shelf's introduction lists dimming among the things it compares; this page lists a swivel, a bracket, a temperature and a warranty
Flicker	NOT MENTIONED
Power options	NO BATTERY AND NO SUPPLY DESCRIBED. The page names no cell, no capacity, no runtime, no mains adapter and no USB standard — it is one of four lights on this shelf with no internal cell, and the only one that does not say how it is powered at all. For a table-top pair used beside a light tent that is a question for the seller
Mount	A RETRACTABLE SPRING BRACKET that "can neatly be folded away into the base of the circle spot light itself", with a STAND per light and a head swivelling 180 DEGREES up and down. A stand that disappears into the lamp base is a genuinely good idea for something that lives in a drawer between uses, and the 180-degree swivel is what lets a tabletop spot be aimed down into a light tent — which is exactly what the fourth bullet says it is for: "Fit most of table top studio photo shooting tent light cube diffusion softbox"

What people ask before they commit

Lumens or lux — what is the difference?

Lumens are what leaves the lamp; lux is what lands on the subject. A 600-lumen source squeezed into a narrow beam can produce more lux on a small area than a 2,000-lumen panel spread across a wall, and the same 600 lumens spread wide produces very little. Converting between them needs the beam angle, which this page does not publish — so the figure cannot be compared with the 800 lux at 0.5 m (1.6 ft) of the ULANZI VL49 RGB or the 1,090 at 0.5 m (1.6 ft) of the NEEWER SL90C on this shelf. This shelf's introduction asks for lux with a distance for exactly this reason.

Gels instead of a bi-color panel?

Cruder, cheaper, and in this case the only option. A bi-color panel fades between warm and cool emitters, so changing the temperature costs nothing but a little output at the extremes. A gel subtracts: an orange filter in front of 5,500 K blocks the blue end to make the light warmer, and blocks it to the tune of a stop or more. With six gels — two each of white, orange and blue — you get a warm, a neutral and a cool setting per light, at a cost in brightness. On a tabletop at thirty centimeters, where there is light to spare, that is a reasonable trade.

How do you dim a light with no dimmer?

Distance, gels and switching one off — and that is the honest answer on this page, which publishes no dimming of any kind and is the only light on this shelf that does not. Moving a spot from 30 cm (11.8 in) to 45 cm (17.7 in) halves the light on the subject, which is the most precise control available here. A white gel costs a fraction of a stop and a blue or orange one costs more. And with two lights, turning one off halves the total. For product work on a bench all three are workable; for anything where the light has to be balanced against a window, a dimmer is what you want and there is none.

EMART EM-7W-LTL, two spotlights, 600 lm each	$30	600 LUMENS PER LIGHT — and lumens are not lux. Lumens measure the total light LEAVING a fixture; lux measures how much ARRIVES on a surface, which is why this shelf's introduction asks for lux with a distance. The two cannot be converted without knowing the beam angle, and no beam angle is published here.

Torjim TJ-RGB, two lights with stands	$35	NEITHER PUBLISHED. No lux, no lumens, no distance, no wattage — only "70 LEDs of high performance" per light. This shelf's introduction makes output the first figure, and on a pair of lights sold as a studio set rather than a pocket fill the omission matters more: a panel on a 57-inch stand is two meters from the subject, where illuminance is a quarter of what it is at a meter	3000K TO 6000K, stated, plus 16 EXTRA Colors beyond the cool and warm whites. Three thousand kelvin is warm tungsten and six thousand is a cool daylight, a 3,000 K span — narrower than everything else adjustable on this shelf except the published NEEWER pair. Sixteen fixed colors is not the same as an RGB panel’s 360 degrees of hue: the NEEWER SL90C and the ULANZI VL49 RGB here mix any shade	CRI 90+, stated — the WEAKEST index published on this shelf, level with the EMART spotlights and the ULANZI K20 and behind the 95 of five lights, the 96 of the published NEEWER pair, the 97 of the SL90C and the ALTSON and the 98 of the published Rollei. This shelf's buying tip says to read the index before the output, and above 90 is usable rather than good: the error in a 90-CRI white LED sits mostly in deep red, which is where skin lives	TEN BRIGHTNESS LEVELS from 10 TO 100 PER CENT, "conveniently controlled by wires" — a WIRED IN-LINE CONTROLLER rather than buttons on the panel, which on a light at the top of a 57-inch stand is the right arrangement: you adjust it from where you are standing. And the controller is BACKLIT, "so you can operate the lights even in a dark environment", which no other page on this shelf mentions
VIJIM VL120, 1250 lux with no distance, six filters	$25	1,250 LUX, stated as "the Max brightness illuminance up to 1250Lux" — AND NO DISTANCE. That is the exact fault this shelf's introduction names: "the distance is part of the measurement and a figure given without it cannot be compared with anything". Twelve hundred and fifty lux at 0.5 m (1.6 ft) is a bright pocket panel; the same figure at 1 m (3 ft) would be four times the light, and at 0.3 m (1 ft) rather less than it sounds. Of the nine American lights on this shelf, this is the only one that publishes lux and withholds the distance	3200K TO 6500K, stated as steplessly adjustable with brightness "in one switch" — a 3,300 K span, which is the narrowest of the adjustable panels on this shelf bar the published NEEWER pair’s 2,400 K. Three thousand two hundred kelvin is tungsten and 6,500 is a cool overcast daylight, so the range covers indoor and outdoor and does not reach the candlelight or deep shade of the ENEGON and the ULANZI VL49 RGB	CRI 95+, stated in the title and the first bullet, with the consequence spelled out — delivering accurate color reproduction and reducing the workload of post-production grading. That is the right way to sell an index: not as a number but as hours not spent. Ninety-five is the shelf median; 97 on the NEEWER SL90C and the ALTSON, 98 on the published Rollei. No TLCI	10 TO 100 PER CENT, STEPLESS, "adjustable in one switch". Stepless is right; the floor is not — ten per cent is as dim as it goes, where the NEEWER SL90C and the Glendan-style panels reach zero. A light that will not fade below a tenth cannot be faded out on camera, and as a background accent ten per cent of 1,250 lux is still a visible source
ENEGON Bi-color panel, 2500–9900 K, 20 hours	$39	NEITHER PUBLISHED. No lux, no lumens, no distance, no wattage — in five bullets. What appears instead is "180 high lumens LED lamp beads", which uses the word lumens as an adjective for a bead rather than as a measurement of the fixture. This shelf's introduction makes output the first of three published figures a continuous light is compared on; this page gives none of it, and five of the ten American lights on this shelf share that gap	2500K TO 9900K IN 100 K INCREMENTS — the WIDEST range on this shelf, a 7,400 K span, against 2500–9000K on the ULANZI VL49 RGB and the published Rollei and 3200–5600K on the published NEEWER pair. And the increment is published, which almost nothing here does: 100 K steps means 75 positions across the range, fine enough to match a tungsten bulb or an overcast sky by eye. This shelf's introduction warns that a mixed panel peaks in the middle; with no output figure at all, there is no peak to be lower than	NONE PUBLISHED. No CRI, no TLCI, no index of any kind, and this is the ONLY page on this shelf to omit it entirely — the published RaLeno gives CRI 95 or better in its fifth bullet, and the twelve other pages here all publish a figure. This shelf's buying tip is unambiguous: "read the color accuracy index before the output figure. A dim light with faithful color is easier to work with than a bright one that turns skin green." On a bi-color panel mixing warm and cool emitters, the index is also where the mixing shows — a cheap mix can be visibly green at the middle of its range, which is exactly where it will be used	1 TO 100 PER CENT IN 5 PER CENT INCREMENTS, stated — twenty steps, and the increment is published where most of this shelf says only "dimmable". Five per cent steps are fine enough for practical work and are not stepless: the NEEWER SL90C and the published Rollei dim continuously, and a stepped dimmer cannot be faded on camera

What sets the models apart, in photo equipment

If price decides: VIJIM VL120, 1250 lux with no distance, six filters, at $25.
Highest Color temperature range in the table: this model (5500 K, FIXED, described as a "perfect daylight temperature" — and then the mechanism that moves it: TWO WHITE, TWO ORANGE and TWO BLUE GEL FILTERS, two color gel filters, stated to change the kelvin temperature for cooler or warmer photos. That is color temperature by subtraction rather than by mixing: an orange gel in front of a 5,500 K source makes it warmer and dimmer, where a bi-color panel fades between emitters and loses nothing. The ULANZI VL49 on this shelf is the only other fixed-temperature light here, and it has no gels).
This model holds the table’s highest figure for Color temperature range.
