I was back looking again for some cheap ebay led lights to fill out my main lighting and found some descriptions that I do not understand.
For example from ebay ad http://www.ebay.com/itm/121140140633?ssPageName=STRK:MEBIDX:IT&_trksid=p3984.m1426.l2649
"Wavelength: RED: 630nm 660nm ; Blue:440nm 460nm"
so what confuses me here is are the red leds 630 nm or are they 660 nm or they multiple chips or do they simply not want to specifiy (so they can include whatever is cheap and available? I have seen this language on many product descriptions and it is defintely bad english.
It was my understanding that single non-phosphor leds have a range around +-10 nm.
Has anybody purchased any?
dazed and confused.
