Hydro Crunch 315-Watt CMH Grow Light Socket Adapter PGZ18 Converter for E39 Mogul Base

Not much to it. Works excellent.

These bulbs are the worst I’ve ever worked with and I’ve been growing indoors for over 20 years. They blow out as soon as your ballast get to or even near full power. Don’t waste your time or money because there is no warranty and the return time is limited. My only advice for people that do end up purchasing these lights is to run them within the first couple of days you receive them so you can return them before the small window of opportunity for return closes. I bought 5 bulbs and they all burned out within the first 15 minutes of running them.

Fits Phillips bulb on basic reflector.

Works good

These fit Phillips cmh bulbs really well. No complaints.

Be sure this will fit the bulbs you're using before you buy! The CMH side or PGZ18 socket is really deep, too deep for some big-name-brand bulbs to fit. Having better luck with shallower-socket style adapters; we want them to work for whatever bulbs we run in the future too.

So far I have yet to receive one unbroken.. Last order I added a pillow to the purchase, figuring that would solve the breakage problem, pillow in big box.. little ceramic thing with pillow....BUSTED AGAIN.... TRYING EBAY NOW..

10/10 for function and price
