Shipping by UPS is ok although basically. The tubes per se also do their following purpose, but I have normal daylight tubes hanging in the room and wanted to gradually convert to LED to save money. The LED tubes have, compared to the normal peaceful Violet light and the brightness is also not as good as described, I find. Email Contact the seller is very bad. One writes his request and get an answer back that has nothing at all to do with the concerns. I'll post this for me tubes under Josh and buy in future brand tubes from the specialized trade. Are more expensive but you angry not so much around with.
