low cost LED lighting designed!

[Icefire]

I posted a thread in DIY about it.

I finished my Driver circuit to drive 100 Luxeon K2 (5W) on a 6 feet long tank.

I can add as many LED I want, It's 95%+ energy efficient, analog (no sunset/sunrise/clouds that are just gizmo).

I made a rought estimate of 1200$ for a 500W 100 leds, 72" long, white and blue controlable 0-100%, selectable moonlight intensity/color. (if I was to sell any)

10-25 years light life (50000Hours), power supply easy replaced if it fail.

Your thought?

100 bulbs over 6ft is not going to light the entire tank also how would you solve the problem of spotlighting and buinrng that comes with LED
what reflectors wil you use?

 

[kodyboy]

interesting

 

[greg10]

sounds like a great idea. just control the heat and/or avoid overdriving and you won't get burning.

anyone have a link to the post in DIY ?

100 five watt luxeon leds would definitely be enough to light a 6 foot tank, have you ever seen a 5 watt luxeon led? With that many leds he won't have any issues with spot lighting at all, it will be very uniform.

huh 500w spread over 6ft doesnt seem like allot but i am usually wrong

 

[kodyboy]

500watts in LEDs would probably be pretty damn bright, I don't think the solaris units have that much, but I could be wrong too

Solaris use 150 3W leds for a total of 450W ON 72" http://www.solarisled.com/Specifications/tabid/67/Default.aspx

I was planning either cheap lens/reflector, fresnel lens or go with Seoul P4 leds, 240 lumens/leds, available in 55 degree beam.

I was thinking 4x25 leds row, over 8-12" wide.

Heatsinking and fan will be there

almost 50-60% of the cost is the leds alone..

 

[greg10]

leds are very efficient compared to other types of light, so you get more lumens per watt

Do you have any of this done? The DIY thread doesn't have much info (two posts and no pics of anything finished or in the works). Don't get me wrong it sounds great, just wondering if you have anything working yet or if you are still in a planning stage.

 

[Icefire]

I made/tested the circuit, only need to do it full scale.

It's pretty simple, power supply, driver board, leds.

I could make some DIY kit, but proper care must be followed for heatsinking of leds.

Icefire I pm'd you

pm'd back

Icefire: any updates? Any pictures of your finished product?

the 3w LEDs are far more cost effective IMO. if the driver is cheap, Id stil with 3w and just increase the number of LEDs for more light.

this might change when you get into bulk pricing, I only know the single LED prices, if your buying by the reel or larger, who knows.

The new Solaris H4 used 150 5.5w LEDs for a 6ft fixture. The G series has 150 3w LEDS.

Solaris H4 uses 600watts = 150 x 4watt LED's for a 6' fixture.

Nope, I don't have the money to build one, I'm automating my reef with a PLC.

The driver I had designed (dunno where my paper is) was cheap, but leds still cost about 1$/watts min + power supply + drivers + heatsink.

Ice fire I never got you the price of the led lights because my customer forgot to call me back.I can go to his house and try to speak with him if you like to see what he can do,I just didn't bother because I thought he was busy
