Hps question.

[Chefbjy]

Hey all hope everyone is well. I was wondering if anyone has run 1000watt bulb on a dimmable ballast at 600watts. The guy at the store told me it would have negetive effects on the life/longevity of my bulb. I don't know if he was trying to save me money or just make a sale. Is what he said true?

I know for a fact that there are no safety precautions to doing it. I dont think the bulb would hit the corect spectrum though with the partial power but you should still get the equivalent of 600 watt bulb outta the 1000.

Yeah sometimes its hard to trust that people arent trying to make a buck on you. The light should work just fine. Honestly I think it would be the opposite anyway. The bulb should last longer. Bulbs go bad because the filaments break down over a period of time from usage. 1000s are set up to handle a lot more incoming power so it would be likely the less power would actually degrade the arc wires faster getting less wattage.

Yeah I didn't intend on purchasing another bulb. But looks like I'll have too get an hps one too now since I only got the mh. Thanks again.

For sure, no problem man.

Yes the potential reduction in bulb life could be because of the reduced bulb temperature.

I ‘ve gdone the same thing with HPS...1000 bulb at 600. Get horticulture bulb 600 and run it at 600 on ballast . 1000 was too hot for me. Keep your adjustable ballast.
