First a list from wiki about Lumen
Read the whole article so it make sence, less u are a physics major

Envirolites LED are effective, energy-saving, reliable, low heat generating horticultural grow lamps, giving excellent results and lower operating costs for all indoor growers.
Plants need light in the correct spectrum, which is proven to be between 400 & 700 Nana Wave, and Envirolites produce high output light in exactly this spectrum.
There is no wasted light, unlike HID and HPS lamps were much of the light cannot even be seen or used by the plant.
Envirolites give 100% PAR (Photosynthetically Active Radiation) high output light and are used successfully for all propagation, vegetative or flowering stages.
Envirolites do not generate excessive heat and can be used directly over plants. This is the secret of growing with Envirolites, positioned directly above, just 3 cm or 4 cm, the top of the plants! Unlike HID lamps, this new generation, grow lamps will not burn your plants.
This is a real advantage compared to growing with HID lamps, as there is no wasted light, which occurs when HID lamps are positioned high above plants. Envirolites give 100 % PAR, correct spectrum, high lumen light directly on top of your plants - where they need it!
Yes a MH can have as much as 1000 W(LED maximum of 250). but since heat will force u rise e, high above, even with CoolShade.
Thus makin u loose alot of lumen, Each feat is 50 & loss in lum.
I currently use 2 MH 600 coolshade lamps, and need to have them about 0.8 feet from top of plant. thus loosing my initial 55,000 lumens to 27,500
I Also use 2 250 W LED that have , and since i have them 1 inch from not loosing any Lumen i have 20,000 lum, which is what make the crop bigger right? and all of the light produced is being used .
6100K Propagation & vegetative growing is what the 250 LED will give ya.
it will give a little less Lum compared with the 600 W MH a 400 MH is the roughly the same as 250 LED in LUM. But not par. and since we realy want the light we pay for to be used is it not smarter, it is a bitch in my opionon serial combining the fan systems with the coolshade.
I use Chronic , in veg mode , gonna have em as mothers. and , do the little loss of lum but significant gain in PAR with LED , and much less heat make a LED more efficent economicly and workwise. I am a layman in this so if my number are incorrect please correct me. I notice also that the plants under LED stretch the same amount per 3 day. so no prob due to the lamp being so close.
