Hi there, I hope someone here who has used MH lighting can answer a few questions for me.
I've bought a MH 150W light with control gear off ebay. £30 all in and the bulb survived the post good deal eh?
I plan to use it over a 4ft fresh water tank of mine in place of the three 30w tubes I currently have. The tank is planted.
I have the kit on test in my conservatory (away from anything flamable
) and all seems ok.
1) While the tube warmed up there was a little hum from the control gear. Now the tube is at full brightness all is quiet.... is that normal?
2) How hot do these things really get? If I mount it over the tank the light will be suspended about 3" under a wooden shelf.... thoughts?
3) The current bulb in it give a pure white light.... any guesses on what colour temp it is?
Any other gottchas when working MH that I should be aware of?
Thanks in advance.
