There are several tubes like this one on Amazon (RMJ, Ambertronix, TaoTronics and Fugetek are the 4 brands I know of). They look the same except for the logo printed on the base plate. I have several of these because I like a *very* bright workspace. But I wasn't sure which one to choose. So I got some "others" to compare. This (RMJ) is about 600 lux dimmer than others using the same settings in the same environment and with the same light meter. The color settings are about the same as others, but they're all pretty inconsistent, although it's most likely the same lamp from the same assembly line with different stickers applied depending on the company ordered.
