MH 600W Metal Halide Single Ended HID Grow Light Bulb Lamp High PAR Enhanced Blue and Violet Spectrums for Hydroponic Horticulture Vegetative Growth,CCT 6000K,55,000 Lumens,E39 Base

Looks NEW, AND USABLE.

I've used these for my bud cycle for a many years. I find that with pure sodium I get longer skinnier buds with these I get long yet fat buds. Wonderful option for buding or growing. Great light spectrum

This bulb just blew up on me. I can’t imagine what would have happened had I not been sitting nearby.

good quality/ good price

I've now ordered 2 of these bulbs, and both came well-packaged and in perfect working order with no defects noted. Packaging included an oblong cardboard box (padded with styrofoam and bubble wrap inside) that contained the bulb itself, which was then packed in the larger Amazon cardboard box, which was also padded with air-filled plastic pouches. Can't speak to the longevity or ultimate value at this point, as they've been in operation only a couple weeks. But so far, so good.

Awesome light and like the price and quality it was shipped well no problem thanks 👍

Quick and easy

The bulb is rated to last 12,000 hours. Time will tell. The bulb is very bright in the blue spectrum and is supposed to be ideal for plant growth. I'm using mine in a small green house to start vegetables for a summer garden. It's too early now to determine the bulb's effectiveness.Addendum: After a few weeks of use, the bulb abruptly burnt out and had to be replaced. Amazon promptly replaced the bulb. I was able to return the defective bulb to Amazon at no cost to me. I hope it lasts longer.
