ReplyDelete1. Does the same setup 3 x led enough for my setup?
2. Is your setup hot after long run?
3. Should I use 1000ma led driver or anywhere in the range of 350 to 1000 will do the job?
Thanks,
Mohan
I don't know. I don't even know whether 3x3W is enough or too much for my tank. Not until I try it.
DeleteI'm running my LED with 900mA and it is not that hot, around 45C after running for 8 hours.
Yoz! I'm living in Singapore.
