White LED, crazy idea... or not?
I have this cute little white LED flashlight and was thinking about building a panel of white LEDs and trying that as a portable light for ENG-type work. Then searching around the 'net I found a whole range of flashlights which use white LED technology... even one with 60 LEDs and a nice hand grip, advertized as good for underwater video. Any chance this can be good for general videography? Is this kind of light really full spectrum and usable with the white balance available in semipro DV cams? Is flourescent better for some reason?

They are the lighting system of the future, go for it!

I looked into this a while back.
What you suggest is already available on the market. At nearly $5 per LED in small quantities, these lights are generally high priced for do-it-yourselfers. Still, they could save on battery expenses and weight. |
Charles Papert, I believe, used one on 'West Wing' and provided a link to the manufacturer recently.
|
Does anybody know of availability of white LED lights in the Vancouver, BC area? Perhaps a store that sells scuba diving equipment...
|
It has been said that you can buy the LEDs on ebay for a lot less than the stores charge.
Try there. |
Yes Mike, it has been said, but I don't have easy access to a credit card at this moment and my sister will be in Vancouver for a short time frame, so shipping dates can be a problem (has been in the past). I would much prefer to buy, in this case, one of those waterproof multi-LED things designed for underwater use from a specialized store in the area.

Try a sporting goods shop. Any place that sells weapons and gear to the police will also have the LED flashlights.
|
I'd try electronic surplus stores.

Look at this bulb replacement
DB640-0IW-014M is the part number at $76 per. 40 white LEDs per bulb. Meant for automotive bulb replacements.

Wow, look at THIS ONE! :

Try and get some Nichia's if your going with the small ones. I've found the white they produce mmm.. less brown.
Some guy made a cool light using a sony camcorder battery on dvxuser.com, no 'resistance' needed because the battery is 7.2 volts so wire 2 in series and those in parralell (if memory serves me). You need a plate adapter for the battery, if anyone knows where to get such a thing please post. I find these lights to give a hard shadow line and the light they produce to be diffrent looking than normal light. Can make a great effect. An add-on diffuser might help. Happy soldering, fun project! |
This one isn't bad for those who want to light inside vehicles:

Brookstone has it
Hi
Your local Brookstone might have something thats usable. I am trying to get one as a part of my guerilla lighting kit. Take a peek at: http://www.brookstone.com/shop/product.asp?product_code=446716 NEW 20 LED Worklight Brookstone sku # 446716 Super-bright worklight has 20 powerful LEDs and a pivoting head to deliver the right light in the right direction. Super-extended battery life means light works for 80 to 160 hours continuously. Rugged plastic/rubber construction makes it even more versatile. Two modes of operation: 10 LEDs provide bright, broad light; 20 LEDs provide ultra-bright area light. Durable LEDs never need replacement because they’ll last more than 100,000 hours of continuous use. Rubber on/off switch makes light easy to activate. Uses three D batteries (not included). |
