What happened with these?

forget semantics, how about simple benchmarks? Micromole per joule (watt). HPS is 1.9, CMH is 1.8, LED is all over the place but the best ones go up to 2.7. But HPS is hardly obsolete, 1000w HPS lights still dominate commercial greenhouses. LED saves electricity but still costs 4 times HPS.

The very best 600w HPS from Gavita or PL Light is around $400, the 1000w $550, 1190 and 2100 umol/J, bulb replacement every 2.5 years, so only another $80 for 5 years of operation. Only another $160 to run from years 5-10, etc.

LED cannot save electricity, see attached pic in application. FL300 is 630w LED made in Denmark, it only supply 90PPFD from top of greenhouse. Tomoto greenhouse usually use 1000w DE to get 200PPFD, so if we also want 200PPFD from this LED, we need the power 630w x 200PPFD / 90W=1400W LED only effevtice when it close to plants.

hps is not 1.9umol/j.

SE HPS pushes 1.0-1.3 umol/j

CMH is pushing 1.5-1.7umol/j

DE hps is pushing 1.7 umol/j

crappy leds like vipar/kind (blurple) 1.0-1.5umol/j (depends on the brand and diodes used)

cobs are pushing 1.9-2.2umol/j

quantums are up in the 2.0-2.7umol/j

This is all according to white paper studies and sphere tests I've seen. I'm not a scientist, just wanted to clear that up.


I have preordered one of these 600w CHPS lights. It looks like it can be a good flower bulb, it looks like its going to be hot as fuck. I'm going to compare it to my 630w CMH, 720w cxm-22 cobs and my 780w vero29 c rigs.

I'll be posting about it when i get it. Should be like beginning of Feb

Im kinda stoked about it, heres why. All these lights we use are made for street lights, warhouses ect then they have been tweaked for horticulture. Save for some of the higher end LED diodes. Hortilux has built this light from the ground up with growing in mind. As far as I know, there is no other CHPS light anywhere. So, it could be pretty baller!

What you bought are real HPS grow light? I can make SE and DE both at 2.2umol/j, see attached

When I saw the CHPS full of infrared, I don't think it fit for plants, too much heat. Maybe can use in shower room.

sounds good - which bulb and fixture are you using???

 

[Alexphillips]

you need to manage the heat released by it. it will be ok to grow plants with 600W but the problem is dissipation of excess of heat.

normal life span of bulb is over 20,000 hours.

Bulbs made by us, fixture from welthink.
