Genaray GESPLR SpectroLED SP-LR review

lightwithtripodbagAs a documentary cinematographer, I’m a big fan of available light. However, it’s rarely perfect. A little fill on the shadow side of a window, for example, can create magic out of a monster. So wouldn’t it be nice if there was a light small enough to take with you anywhere, that you could just snap your fingers when you needed it?  Or like, wave a magic wand?

When first I saw the IceLight from Wescott, I felt it wasn’t quite right for a couple of reasons. One, it wasn’t powerful enough. Two, it felt overpriced to me. So I waited. Given the rapid pace of LED development, I knew it was only a matter of time before we’d see an exciting development. In fact, I’ve been Googling for it. When a recent search for “IceLight alternative” uncovered something called the Genaray GESPLR SpectroLED SP-LR, I was interested. When I saw it contained both tungsten and daylight balanced lights, I was impressed. When I saw it was listed at $250 (half the price of an IceLight), I was sold.

caseThe light arrived a couple of weeks ago, and the first thing that caught my eye was the case. It’s one of those padded, semi-hard things, solidly built, something I will actually use. The size of the light is nice and compact, at just under 22″ long. The active strip of light it produces is 14″ long. It tucks easily into my Porta-Brace tripod bag (with the tripod in it, too), which will allow me to carry it easily on the road.

tubehandleThis light is impeccably professional looking. The black, all-metal handle includes buttons that electronically switch between tungsten and daylight, and dim the unit from 100 percent to 10 percent.

The mode button switches between tungsten on one side of the light, and daylight balanced LEDs on the other.

The dimmer works well, and produces no audible buzzing or sound of any kind (yay). Also, the light is flicker free at all settings.

The light is advertised to last for 2.5 hours at full blast. I found that not quite true. After running for 1.5 hours, I measured a small dip in brightness. After 2.5 hours, the light was still running strong, but had further dimmed, losing perhaps 1/-8 to 1/4 of it’s original brightness. At 2:40 it was down to 1/2 original power, before dying completely at 2:46. So it dies with a whimper.

This is a drag. I’d far prefer a light that dies with a bang, so that I could count on it being consistently bright whenever it’s on. Still, the fact that you can get in excess of 3/4 of it’s power after 2.5 hours isn’t too shabby for such a compact light. It’s just one more thing to keep track of during a shoot. For those reason, I’d recommend powering it via the AC adapter for longer interviews, or if you’re doing multiple interviews, for the later ones.

The battery is built in, so it’s not possible to pop in a spare when it runs out. An AC adapter is included, however, so you can run it all day off the cord, which also charges the battery.

The light features a 1/4″ 20 female mount point in the handle. The included mounting spud has 1/4″ 20 screw on one end, and 3/8″ on the other. This makes it easy to attach to various mounting hardware such as tilt brackets that allow you to fly the light over camera for use as fill, for example.

c-standadapterTo hang it off the arm of a c-stand, you’ll want one of these little guys (photo at right), a Manfroto 5/8″ to 1/4″ 20 rapid adapter. The light itself is so light (just 2 pounds) that it’s actually possible to hang it off a regular light stand, using a Photoflex heavy-duty grip swivel with a stand extension.  In that scenario, you’ll need to counterweight the bag. However, using a c-stand (below) you can fly it anywhere without counterweight. Which  makes fast and easy to reposition the light between setups.

One gripe I have about the design is that, as shipped, it could use more diffusion. But it’s easy to add. Wrapping it with Lee 1/2 white diffusion softens it beautifully and completely eliminates the dreaded LED multiple shadow effect. The penalty for this is a full stop of light loss. However, given how bright it is,  this could be been seen as a positive, since the light doesn’t dim below 10 percent. If you just need the extra stop of light, it’s there.

Brightness

For such a compact light, it packs a big punch. (However, it loses some of that to color correction, as we’ll discover in a moment.) How bright? Here’s a real world example. After color correction gels were applied, I was able to set f/2.8 at 6′ with ISO 800 at a 48/sec shutter (24p). When dimmed fully, I read f/1.0 and a half. The tungsten side is about a third of a stop brighter due to needing less color correction.

Versatility

You can place the Genaray just about anywhere. With gaffer tape, you can affix it inside a car, for example, to get relatively soft illumination where you want it while hiding it from the camera.

The light has a rather nice, softly directional falloff, like a Kino-flo tube (more on that in a moment). I found it easy to feather the light by twisting it, and cutting it further is possible by applying black wrap.

This is the light of a million uses. Here’s a few that I’ve tried.

Back light: Because it weighs just a couple of pounds, you can put it on a light stand with a swivel grip and stand extension, and boom it. I have a 7-lb Steadybag that is heavy enough to counterweight the light in this scenario (photo at right).

Fill light: Again, it’s so easy to fly this light directly over your lens with a light stand, where you can use it as a subtle, relatively soft fill.

Kicker: Simply screw it on top of the 1/4 20 thread of any light stand, and you’ve got a vertical strip of kicker light, that can chisel out some definition in an otherwise flat interview.

Traveling shots: Screw it onto the end of a Mogopod and you’ve got yourself a light boomed for traveling shots. It’s not as bright or as soft as the BBS Lighting Flyer, but then, that kit will set you back $3,499.

Bonus: Skype light. Just stand the light vertically on the counter behind your laptop to illuminate your Skype conversations:

Illuminating your next Skype conversation is as simple as placing the Genaray upright on your desk.

Bonus: Camping flashlight. This light works great to light up a campground picnic table!

So without doubt, this is a very flexible light. Great. But how does the light look?

Color accuracy

The Genaray is advertised at 3200K and 5600K. Previous inexpensive LEDs that I’ve reviewed have been all over the place with this. So, what can you expect out of a $250 LED these days?

5600kdefaultOn the right is what the vectorscope shows me at 5600K (a perfect balance would place a tight dot in the middle of the scope). So it’s immediately clear that we’ve got WAY too much red. We can correct this by adding a little CTB and a lot of plus green.  We’ll find out just how much in a moment. But first, let’s see how the 3200K side of the light stacks up.

3200kdefault

The 3200K LEDs, shown at right, are much closer to proper color balance. However, there is still a noticeable magenta shift. For a photo light, I want to see that dot in the bullseye. So we’ll need to add some plus green to get dial it in.

NOTE: I used an 18 percent Kodak gray card to do this test, and Magic Lantern’s Vectorscope on my 5dmkiii.

halfgreenblueOK, let’s tackle fixing the 5600K side first. After much testing, here’s what I came up with:

+ 1/2 green
+ 1/4 blue

Now we’re erring slightly on the yellow/green side, but just barely. And that’s the side I prefer to err on, because skin tones always look better a little yellow than any other color. I tried adding 1/8 blue, but that put us too far over toward blue/cyan. So this is about as close as we’re going to get this light, given that filters come only in 1/8th increments. Also note that this reduces the  output of the light by a full stop in 5600k mode.

plusquartergreen3200Fixing the 3200K was easier:

+ 1/4 green

I think it’s a shame these lights don’t match the color temperature they are advertised. But not as much a shame as paying $500 for the IceLight2! The price of inexpensive LEDs, at present, seems to be color temperature accuracy. But as you’ve seen, it’s possible to dial them in with a little work.

The CRI is 85 on these lights, which means colors won’t be as faithfully reproduced as with higher CRI sources. But in my experience, 85 is plenty high enough for general documentary use. My guess is that these lights are probably all different. So you will likely have to do your own testing to correct your copy of the light.

Light quality

OK, now that we’ve corrected our color balance, let’s take a look at the light qualitatively. That is, how does it look on a human face?

The closest thing I can compare this light with is a Kino tube. Only, minus all the crap you have to pack around to get the Kino fired up. It produces the same signature shadow as a Kino tube – soft on one axis and sharp on the other. So it’s an interesting mix of hard and soft light.

If you hold the light horizontally above your subject’s forehead, it casts a sharp shadow under their nose – but spreads soft light across their face from left to right.

Genaray held horizontally

Flip the light vertical to the subject, and you get soft shadows under the nose and chin, with rapid falloff of light on either side of the face (you also get nasty vertical glare on glasses, which is why they aren’t in the shot below).

General held vertically

Used as a backlight, above and behind the subject, it spreads the light across head AND shoulders. I prefer this look to a point source.

So to sum it all up: Despite being pretty far off the mark in terms of advertised color temperature, this light can be balanced with a little effort. And it’s effort that will pay off. For the price, you get a lot of light in a tiny package that can be put to work on just about any documentary shoot. Especially for travel, where space and weight are always a consideration, this light is a road warrior’s weapon.

    Fantastic review – thanks. I’ve also been on the look out for something that may be able to compete with the ice light. I’m adding this to the list. The mogopod is a new one on me but that looks worth a look too!

      Hi Rob,
      It’s definitely a contender, Rob. I would like to compare the IceLight2 with this one head-to-head, in particular to see if the 95+ CRI of the IceLight2 makes that much of a difference in actual use. But until someone sends me one, this is all my budget allows at the moment.
