has anyone used these?whats your opinion? im looking at lighting for one of my 300 shttp://www.ebay.com/itm/Aquarium-Reef-LED-Lamp-50W-10000K-White-350W-Metal-Halide-alternative-Light-/271091361358?ssPageName=ADME:X:RTQ:US:1123
Yes the 50W are super bright, but the problem is they tend to focus light on one area, so they dont have a very wide spread if its for a planted tank...
Otherwise they do look good but would likely need a few to get good light coverage over the whole tank...
Tip: if it has the pinkish glow and does not indicate super red as its color scheme, it is bad. Most SMT LEDs nowadays offer 180° coverage. Discreet LEDs don't.
