 Hydroponic ballast for halides?
Hello all. A few years ago I tried metal halides. 2-175W 10k bulbs plus a NO actinic on my 65. I used two hydroponic light ballast and for some reason I could look directly at the bulbs and it they did not seem very bright. I mean in all reality it looked like the tank was light by 3-NO actinics. Was it because of the ballast?
The reason I ask is because looked at a 10K 175W at my lFS and it was so bright I could not look directly at the bulb. The bulbs were used for like two weeks then put in storage. I was planning on using one on my 20H but before I buy a ballast and reflector and fans, is it just the bulb. It is a 175W 10K blueline bulb.
Let me know!
BTW, I ran a 250W 14K on my 10g and it was EXTREMELY bright. Either it is the bulb or the ballast!
