    I really like to build my own stage stuff for gigs. Years ago I started patching wooden panels to a mixer desk. I actually like this easy way to get customized equipment that's why I decided to get my own handmade lighting hardware.

    That's my plan:

    I get some of these LED bulbs (see details) - about 50 lamps. They will be embedded in light wood with reflecting foil. That's the point when I put them together electronically to control each LED individually.

    Question:

    Well, there will be 50 LEDs shining on full power... What do you think about the heat? Will the temperature be scaring (keep in mind that there will be wood and plastic foil)?

    On those bulbs? No. They are very efficient units.

    Is that the best solution? No.
    Reflective foil? Are you joking?

    Get less but more powerful LEDs - which would require proper heatsinking and metal mounts.

    LED lights emit very little heat..............we've just changed to LED lights, they save you a fortune in energy..........not cheap but worth the investment........they are 4.9 watts each and they are incredibly powerful, they are also cold to the touch so no chance of being burnt.

    Hope this may help you in some way.

    Cheers

    is not awfully true. The average LED converts power to light/heat with about 70% being heat, you are just running very very very low power LED's.

    Powerful LEDs get extremely hot infact it is the main reason the technology has not replaced household lighting yet.

    GU10 and MR16 which are the usual halogen type down lights are the first to be converted but still fall short in lumens (total light output measurement) even though the entire housing is a heat sink.

    If you have space to dissipate the heat in a heat sink then there are LEDs available with outputs over 1000 lumens that is very bright the difficulty comes when you try to control the light it is a diode and has to be controlled by a specific LED dimmers or it will just switch on and off.

    I did a promo video for Texas Instrumnets last year showing how to dim LEDs with a zigby wireless controller It can be done but it is not as straight forward as you may think. Oh and the powerful LEDs will be expensive.

    Haha really? I knew most LED's have flickering issues but that's kinda cool!

    Sorry when I said on and off I meant on or off in other words you can't dim LEDs without specific control electronics.

    Also you have to be specific about colour banding of white light and the more specific you re the more expensive it gets although you could opt for the Chinese equivalent and have a lovely brown LED light after just 10 hours Winkhahahaha.
