Pentair PG 2000 light stopped working. Replaced metal halide bulb, worked for a few hours then stopped working and wouldnt come back on. Replaced capacitor, but light still doesn't work. Have verified 150volts to lead wires to light bulb. Any ideas on what might be causing the problem - not enough voltage to arc the bulb?? Thanks!

If no fan, first you check the fuses.

If the fan is ok, no lights, normally it is problem from the ballast and bulbs. Reference is from below.

When you are using a metal halide a glass shield is a necessity. Metal halides get really hot and one drop of water could cause the bulb to explode. A glass shield would also filter out the UV rays.

The metal halide lamps come in two versions the regular one and the HQI version. These lamps are very useful to the aquarist needing a lot of light. Their commonly come in 250,400 and 1000 watt sizes. The bulbs range in lifetime from 6000-10000 hours.

There are several types of lighting for aquariums, each with their own set of pros and cons. The various types include: incandescent bulbs, fluorescent bulbs, PC bulbs (power compact), metal halides and HQI halides.

hi, a word of warning , the ignition voltage of a metal halide( grow light ) is many thousands of volts .
the first thing to try is a replacement bulb , next is replace the ignitor ( usually a small block with 3 terminals ).
a metal halide lamp can often look to be perfect when infact its internally blown .
hope this helps

ballast is weak ,or the bulb. i would never by the combo lights /use a hi pressure sodium for both vegative state and flowering.you dont necessarily need a MH..

well mostly these lights come with a ballast and the right connector to go from the Ballast to the bulb, if you dont have these then it might just be cheaper to get another set-up. these bulbs run at the high end of the spectrum , in the infa red end of it actually , but really are an ineficient bulb like the mercury-vapour that preceded them compared with the later models , lets say from the 'sonti-agros' till now ( a much more usable spectrum of light and more efficient ) there are a huge range to choose from, as far as the scematics of it well they differ from light to light and brand to brand, hope this has been of some help. geoff

if it is a gas bulb (mercury vapor, metal halide, or high pressure sodium) the bulb needs to be replaced. they "cycle" when they go bad for a few weeks then completely stop working

Hello

Replace the fly-eye lens of projector.
