25sqf sounds like a 800-1000W led-lamp

among the 1001 possibilities there is one I can recommend.

watercooled led light

- with integrated heatexchanger.
- if you grow in your house - you could prepare ~ 250L of hot water every day.
- my light-heat-cogeneration is world champion in energy efficiency.
- cheap & easy to copy if you are able to cut and drill aluminium square tubes.

I been looking at the rapid led 5x5 kit.....

You can probably get more value for your money with other COB than CREE.. @CobKits they are sure very good but not the best value.. if youre into DIY look at samsung F-strips and yes quantum boards are very good too but they will get their V2 in couple days/week so id hold on to grab those instead as they will have the same price as the current one and be more efficient

CXB3590 are a waste of money nowdays. At $45 per cob, plus $20-30 per heatsink, you're at $65-75 per COB total. And you'd wanna run at 50w or so.

Samsung F series strips or quantum boards are the way to go. A single 22" single row samsung F series strip PLUS heatsink is $17 or so. And can run up to 50 watts each, and are 177 lumens/w typically.

Check out this thread. 5x5 tent with 900w of strips. His design was WAY overkill, but he pulled 1700+ grams or 1.9g per watt his second grow.

This link has lots of builds, inc for 5x5 with links to parts too

You could do a 5x5 build for $600-700 easily. With CXB3590 cobs, a decent 5x5 build would cost you around $1300-1500 easily. And wont be as uniform and spread.

Just call timberlights and be done with it ...

So overpriced though

LEDgardener has complete part lists with links for led strip builds. AND wiring diagrams. It's fool proof.

You could do strips for half the price as a timber cob light, and it will be a better light.
