LED Light Panels .... Pricey

[StopMoWorks]

Nice..... bright, heat-free, soft output, daylight balanced. For my own purposes, I was thinking for lighting miniature sets, as applied to stop motion animation ..... but .... sheeeeeeeeeeeeesh ..... at $2195. for only a two light kit??!! [ litepanels.com ]

Just thinking if someway to home-brew construct .... do-it-yourself LED light panels :?:

Way too expensive! I've seen the high-output LEDs at my local electronic surplus store selling for much less. In the Houston area they are called Electronic Parts Outlet and there are three here. I think there are similar ones where you are. They can be found advertising in the magazine Nuts-N-Volts.

You can buy 3200K or 5600K white LED lightbulbs that operate at
110 volts for around $30 from here.

These lightbulbs use the Luxeon white LEDs. I don't believe that these
inexpensive products have been available for very long. I was going to
construct my own light to try it out and keep the cost down.

I have not seen a spectrum plot of the Luxeon LEDs. The manufacturer
claims that the newer LED have a CRI of 90, but I have seen other
CRI numbers from other people.
Here is a place where there is some discussion about LED lighting for
film/video.

It all depends on what you want! The Luxeon 3 watt white diodes are around £10 each from most places (small quantity) so if you wanted a panel made up with them the cost would soon mount up- and you'd want something more sophisticated than a series resistor to power them! But they are very bright. Someone told me that those big stadium LED displays they're using these days that use Luxeons cost about £10,000/square metre!
