Metal halide - 175 watts - 7,400 lux - 44watts/sq. ft

LED - 44 watts - 13,300 lux - 44 watts/sq.ft

The LED gave better growth results. Google the following - University of Minn. Department of Horticultural Science LED vs. High Pressure Sodium Test Results (2006)

LOL

you clearly have not used LEDS

try flowering, LEDs cannot penetrate deep foliage or thick buds...its a waste unless your using for baby plants or leafy veggies

[buuust]

led = waste of money and time

HPS will give u more lumens per watt

damn commercial

[cdubcdub]

@buuust look up lumens dumdum. They have nothing to do with a plant's wavelength requirements, they are just what we are able to see

[BDKwiu]

is it healthy for the plant to be exposed to lights for 24 hours a day until flowering?

[bpg2attheh]

yes

[RoadRashBurn]

Yes, but a few hours a day of darkness will help.
