For the price, no need to say the purpose isn't a professional use. I use it inside and permanently installed, so the full plastic enclosure isn't so much a problem, even better, the light weight is a bonus in my case. Talking about color rendering of the QCL LEDS, I am disapointed compared to what I've got with the Eurolite LED Bar-6 QCL RGBW. Even with single color leds (blue, red or green), it doesn't look as 'deep' and 'sharp' as it should do, in my opinion. However, for the price (35 euros), it works and the 40° beam angle is a real benefit for an ambiant light install.
