Yeah looking at the datasheet for: LUMEX -SML-LX1110SOC-ATR HIGH InGaAIP Orange/Red 620nm Clear 2.5 Axial intesnisty:25000 90 degree angle, its not very good!
It's a 1W power LED, but only has 15lm, red can easily be at least 35lm, and the viewing angle of 180deg, although not really needed, 120 deg is standard, but I hear that 30 deg is ideal for growing, you can fit lenses to the Power LEDs to achieve the desired angle.
a420seeker the LEDs in your picture look interesting, where are they from? Whats the driver that it uses? and how many of them would you prospose using? However the output you quoted though can't be correct, there are 3 LED and I guess the output figures are for 1W X 3 so the unit's lumens:
White: 180 lumens
Blue: 60 lumens
Red: 140 lumens
There are only a handful of manufactures that can get more that 150 lm per white 1W LED, Seoul semiconductor being the best I think (but don't quote me ) @ 220lm per 1 Watt LED, and if you can buy them, they aren't cheap at all!
