I bought two of these lamps for my original Bio Green mount me two months ago. Yesterday went the first break with a bang. Since I have contacted the seller. Today, I had just written the email to my seller, the second lamp goes off with a bang broken !. This can not be happening. How can plants for two lamps in direct succession to give up your function within two months ??? !!! We're not talking about 3 euros lamps. No, these lamps cost 15,99 Euro per piece. A mystery to me. I hope I get the seller two new lamps as a substitute. Time will tell.
My last two Bio Green LUM152 held 1.5 years. This did not go out with a bang, but were getting darker over time. Ie over a period of months to read the brightness performance.
Maybe it's a mangehafter China Import or whatever. I can not recommend if the error rate is so high, the lights.
