Not many are over 120K lumens, at that is at the bulb level before losses. MH fixtures are generally less efficient than LED fixtures.
Electronic ballasts are more efficient than magnetic.
http://vi.raptor.ebaydesc.com/ws/eB...tegory=178989&pm=1&ds=0&t=1511511602000&ver=0 Can easily put out 120k lumen, lamp level (claiming 140k lumen, probably 110K protected) 14k lux at 5'8" (do math for candela, nearly 13k x4, typically 4k lux for a good sized wall in the field. ) . Using only 1000 watts. For work application, $200, works great. Before, I used a wall of lights, with lesser results.... For led, you have ac dc loss, huge heat sink loss, price barriers to be broken. The other factor to keep in mind is that inside v. Outside, are completely different animals to light up. Photons inside do not commonly get instantly absorbed, rather bounce around, raising lux to surprising levels, beyond predictable candela rating. Outside, yes, usually, only lux matters. For example, at Sherwin Williams, where we do color matches, it is clear the led tube retrofit is a downgrade that is hard to finger. The engineers only took lux and cri into consideration, forgetting the rest of the photon story after the first bounce-lower lumens, lower worker and shopper light induced alertness, due to lower store lumen level.
Show me a $200ish led light with over 100K lumens, a good form factor, and I will buy. Though I paid only $140 for my second 1000W 120k lumen MH on ebay.
After owning this light and struggling with sub 80k lumen setups, I now know how much light we need. Though, will always be flexible for a small, convenient form factor, or cheap price tag (my 500 watt smd based led light, claiming 50k lumens-30k in reality, is worth $50,but I overpaid $100 on ebay, because of led buyer excitement. My generic 50 watt cob burned out after 2 dozen hours, had to solder in a 100w cob, so far underdriven has worked well-so I don't trust ratings on generic led cob emitters, but dang, so cheap, it is nearly impossible to avoid. )... The 250 watt led 70 deg ,claiming 30k lumen spot for $160 is exciting, until I remember testing my 24K lumen Tota against my 1000W Mh, and seeing no contest. Also, 4x, per data sheet, at $160 a pop, with roughly same efficiency as mh. Nonetheless, exciting to see gaining ground. Just reminding, that, ain't there :yet. But wait 2-4 years, at $50 for 30k lumens, will be there to match my 1000W mh. Though, right now, the target is the lower hanging fruit, the lower low and output of the common 400 w mh, which is a light I own several, but never excited me. And I hate my 150 w MH, but tolerate it to light my garage,feeling it unfit for job use... Also, I would not take lightly that the led light is more suited than my indoor electronic ballasted mh outside in rain,buggy environment, and where only candela and beam pattern matter. Though I do respect quality mh reflector v. A poorly designed one, like on my junkie $20 second hand 150w Lithuania mh,which retailed for a ripoff price.
