Eye Hortilux Ceramic Metal Halide Lamp 315 Watt Made in USA Grow Bulb

Bought a bulb from some cheap company the cheap bulb died in a month. Bought this and it's been rocking my CMH315 grow way better the light is even more intense. BUY AMERICAN if you want quality!FYI THIS WILL NOT PROPERLY FIT A SUNLIGHT SYSTEMS NEUTRON reflector without bending in the tin reflector material a tad bit on the inside. Not a huge deal and worth it..

Altho i think 100 is excesive for a light bulb i have been using it for 2 weeks and have seen masive growth i would say close to an in a day and i love that its a made in usa product

The Good: Nice bright light, the element is literally bigger than a generic CMH. Good light for canna applications.The Bad: This is the second lamp that has small glass shards in the protective glass envelope, its wierd, this is the second bulb like this, seems not to hurt performance or have I had a rupture or breakage. i'm only 80 hours into operation so its just breaking in.

The bulb never fired up, just a faint flicker and then nothing.Notified seller and amazon.....No HelpItem can not be returned... Now i have an expensive bulb and no light

Rated to hang vertical but working fine horizontally....a great 4200K bulb, great results especially when combined with a 3100K bulb in equal amounts..we’ll see if the “extra” UVB makes a difference. Run this one in an open fixture, not behind a spectrum-absorbing pane of glass!

Best 315 cmh spectrum out there, too bad it's a vertical burn only bulb. That sucks!

Eye hortilux 4100k is far better than Philips 4100k. For veg.I've used both and tested par values. Eye hortilux is far superior. However for bloom go for 3100k Philips.

Using the bulb for indoor gardening. Definitely performing to expectations. Worth the extra money opposed to cheaper bulbs and it shows in your results.
