This is not always the case, Evo leds does a 50, 70 and 90 led light that is way gooooddiode brand is pretty important as well. CREE, Epistar, Bridgelux, Xenlux are four of the major players. So is the strength to which each diode is driven. This in part determines the longevity of the diode and is nice to know when purchasing. For reference most major brands run their 3w chipsets to about 2.1w of actual output. One should also inspect viewing angles. Most reputable companies use a mix of 60 90 and 120 degree angles. Some more inexpensive models chose to only use one angle which can make for a shitty footprint and bad penetration.
Cree and bridgelux are more in a list in which I would add Osram Golden Dragon, Ledenjin and Leuxon Rebel..... they are more efficient than epistar and xenlux
Also in case anyone hasn't mentioned it yet a real led light will put out at least 130w of total output, anything else (I'm looking at you 14, and 50w ebay panels) should be considered side lighting at best.
