XAMT Growing Light Bulbs CMH Bulb 315W Full Spectrum Boosting Veg and Flowering

Tested this lamp against Philips 3k and Ushio 3k & 4k. I attached the results from the 4k test as it was the only non-fired lamp. The reason that it matters, It did so well that I thought my 3k must be old! It was not. The 2 lamps followed the EXACT same curve on McCree scale as well.

My bulb burned out. I bought this one and it lit up and then the fixture shut down after a minute. I thought maybe it was my ballast so I bought a new ballast. Did the same exact thing. I bought a different brand bulb and no issue with either ballast.

2 out of 3 did not work upon arrival. They were sealed in the box and the packaging is sufficient. I think there's a lack in their quality control department. The unit that does work, is a decent product. There is simply an issue with quality control.

Didn't even have the bulb for 2 months and it imploded on itself. And it's past my return date. So I'm going to have purchase from another vendor

Fabulous light... Great grow bulb.

Ordered 2 off them . First one came broke, and then the second came broke. BIG INCONVENIENCE

Very disappointed to find that the item was cracked upon arrival.

It came broken

Flickers a lot. Noticed that while doing maintenance. It flickers on the same time intervals.

Bought this product and only works when it wants to .. A waste of money .. Wouldn’t recommend it to anyone ..
