Electronic or magnetic coil square wave? I can't find any 860 or 1000 watt in Canada.
First problem is that Mars is well known to be chinese made garbage. LOL at PAR being bullshit. Its long been an ACTUAL scientifc method for mesuring light, but hey wtf does science know right?
They're designed for use with magnetic ballasts. I don't know if they're compatible with Canada's electric power standards.
Are you taking about the Philips 860W CMH? Those are crap for growing. I had several customers use those and well they use them no longer. If you're not worried about heat or power consumption Get a high frequency 120kh ballas like Agrolux ALF 1000Rt, Philips 1000W DE and a DE reflector and off you go. Or get the Agr0lux ($460 retail or Gavita ($605 retail) systems, although not too happy about how and why Gavita increased the Canadian wholesale price and their own bulbs are way more expensive wholesale then the Philips Green bulbs.
They were crap for growing because of the magnetic ballast. Remember, they're exactly the same tech as 315W CMH. The only difference is the low frequency square wave ballast. A 30% body in efficiency does make a big difference.
Sorry dude but maybe for a closet grow or a few lights but I have 100's of Gavitas sold to guys who are growing some killer looking product that sells for $1800-2300/lb right now in the lower main land were average weed is $1000/lb
I didn't say the old stuff doesn't work. What I said was that it's obsolete. A P-51 Mustang still flies just fine- but in a modern dogfight it's hopelessly outclassed.
Those three lights brands are the best and are what all the commercial light deprivation greenhouse for cannabis use. These lights are very powerful, and you have to keep them always from the plants, but bottom line is they will out produce LEDS at $2400, all day long. If you want to invest and save money, look at Cannapro Light deprivation greenhouses. Complete with 75 of the lights for supplementation, you can get two 36x96 greenhouses, 6200 sq ft, 5500 sq ft usable. You can run them all year round, and get 5 crops, even in the snow belt. You use 1/20 th of the power. Commercial growers light bill went from 30,000 month to 5,000. The complete setup costs $269,000 Canadian as its a Canadian company, complete with lights, and co2 , computer controlled everything etc. and commercial Fogco odor control used on hog farms. You can conservatively yield 4 million per year, gross. The only way to go !!
