Do you know of a LED version of the lowel iLight?

The LED light is due to the light emitting diode, i had studied about that . i think this is called the lowel light. the light bulbs mainly contain the tungsten which is the base of the emission of the light. thanks for the thread,.

Usually when people refer to tungsten, they're talking about color temperature

yes thats what I meant. Carl sorry I lapsed into industry lingo, shooting tungsten meant shooting while balanced to tungsten color temp. The LED revolution is primarily ~5600kelvin so switching to LED's
is mostly about switching to daylight balanced shooting.
 
The led revolution is mostly the bluish 5600K. You are right on that. That is because leds are cheaper, easier and more packageable in them dime a dozen variety teeny weeny ones that are usually found on the ElCheapo units . They must have given leds a bad name. Have you ever noticed that they are always grouped in multiples of 32 like 64,128,256,512 ? There is a reason for that. Easy to assemble from a large blanket of them, cookie cutter method. I hate to tell you that they really are a dime a dozen from where they originate from. Beam angle is always narrow too, guess why ? Because by concentrating the beam to around 30 to 40 degrees they gain brightness but at the expense of spread, yes spread, spread is what you really gotta have when you shoot in 16:9, especially when your lens is racked out to the widest setting. Sure, put a diffuser on that and loose a bit of light, in fact around 50% of it.Now there are leds out there that are not blue at all. As a matter of cact really good ones can be had at any temperature rating from say 2800K to upwards of 8000K and anything in-between. They are also at 110 degree wide spread from the start and also are EACH capable shelling out the equivalent of a 50 watt halogen at that. As a bonus they are way more efficient than those teeny weenie ones .
Only 3 or 4 of these "super leds" in a proper housing can easily outshine, outperform them large 512 led panels that are overly rated as a 500W bulb equivalent (so they claim). Who makes these leds, where can I get em'? Actually they are out there.it is just that they haven't found their way through to a manufacturer that puts them on a tripod or camera. Soon, very soon, they will slowly make their way to the dealer's shelves.
 
Hi Norman. If you use name brand ones you see in B&H like litepanels, rosco or the ones made by Richard at coollights then skin tones are fine. I don't know about the ones on ebay.
they look like a waste of time and money.
edit:
all the interior scenes in this trailer (and film) were with LED's

Hi, if you were originally looking for an eye light, then I would imagine that any compact, low output led might do for that application. Even if the color temperature is on the blue side or on the warm ( yellowish 3200K side ). If you really need it to be somewhere inbetween, there is always the possibility of picking up a gell sheet of almost any correction you want. Rosco at B&H usually has them or can get them, they are cheap, like under 10 bucks for a 20X24 inch sheet that you can cut and gaffer tape in front of any led light you wish. Most led lights out there are NOT in the beautiful neutral light that is like a creamy off white kind of color. Those are few and rare. Those are seldom mentioned as most don't even know exists. No, you have to settle for either too warm or too blue. However, you can always either gell them or do a manual white balance on the camera itself. A blue tint one is great for outdoor overcast cool kind of day when you have to match the subject (usually at close range) to the bluish background. Take that light indoors that has incandescent bulbs, as in restaurants or receptions, and you will need some serious color correction. You may have to "warm up" that bluish led down to 2800K or thereabouts. You're talking around 3000K difference. Not to fear, most led lights already thought of that and graciously provide you with a yellow/amber/warmCC conversion filter so that you can shoot indoors at warm color or outdoors at cool. Also to mention is that outdoors can also be on the warm side depending on the time of day. Just keep in mind that anything you put in front of the leds or any light source will decrease brightness. I would really go for led(s) that are as close to that beautiful neutral white as possible ( 3800 to 4500K). This way the camera does not have to swing too much from one extreme to the other in the color white balance department. If I had to choose, for an eyelight, I would get a small but powerful led that can also be used for other general lighting application such as a side fill and back hairlight. Something in the 1200 lumen department ( 75 watt bulb equivalent). I bought mine off eBay that is a 1700 lumen neutral white that has a dimmer, 110 degree beam and only consumes 20 watts for $499. I also picked up the 900 lumen version of it at $349. They were also available at 5200 and 32ooK and beam angles down to 10 degree spot.I don't know if they still have more of them as this was a few months back. Check out B&H, last time I was there they had many different units on display. I am sure that if you don't find what you are looking for there, you can look up some on the web, tons info and models there.
