My cunning plan was to go from Fluorescent to LED lighting - my maths were the price difference vs energy consumption vs heat utilisation etc..
So I got a 200 + lumen led strip from China as a test.. it does okay as a low light but for the price ($30 or so), wasnt delivering what I wanted. I had plans to slowly buy a whole grid without shewho noticing the packages
I had been interested in HID but the price commitment was higher than I can afford as a test, but a mate just gave me one to test and the results are amazing!
I'm just using a 6000k one, hooked up to a computer PSU but have a couple of questions...
1. The tank cover is about 3" high, and heat is an issue so I have a PSU fan running and that's keeping temps at an acceptable level, but the heat is radiated... hard to explain but it "feels" like a high UV source?
2. I'm just using a single line off the power supply - is that enough to to properly run a 35w HID?
3. Over winter, would it be possible to bleed the excess heat off the ballast to heat the tank as well?
Cheers in advance - and apologies if this has been thrashed to death before, I did a search but didnt see anything.
