Inner bulb went black and bulb would not fire after 2 weeks normal use. Thanks Hydrofarm for using some no name chinese contractor to manufacture substandard bulbs and fail at testing them when you know they cut corners. Wasted money, now I have to pay to ship it back to the poor retailer who has to pay to ship it to hydrofarm, who is going to throw it away and write it off until they get enough complaints. Should have bought an EYE brand or something made in USA or EU.
