And if you look at that pdf I posted above you can see they've put it on an oscilloscope and the signal is nice and clean.

there is only two ways to be sure.

1.do it yourself: a picture or video can be manipulated.

2.nuke them from orbit.


point is: at some point in the line your going to have to trust someone. just buy from good companies, proven products and with good return programs.

Philips built my ballast and the lamp. They aren't interested in short term gains by misrepresenting the performance characteristics of their products.

is this a trick question....

Philips is one of the world's largest electronics manufacturers. They introduced an inexpensive low frequency square wave ballast system, touching off the current popularity of the design. Many secondary manufacturers use their ballasts in their own lamps.

No trick. Just the treat.

IF CMH/LEC has been around so long, like since the 70's

why is now, so expensive, and has the buzz.

they want 843usdm for a double fixture. that's crazy.

why now?

how long have the ceramic lamps been around? i mean the 315' square wave's? i thought they wer newer..had i knew these wer around years ago, i thought i wouldve heard about them.. i read a thing in sep 2013 high times about lighting and thats were i found out the 315's wer as efficient or more efficient than gavita de's 1k.. so i bought 2 wright away,, i wasnt so sure about the claims,, i honestly didnt expect the 315's to do so well..they surprised me, in a good way, 1 315 may not equate to a 600 watt hps, however the more 315's you run the better they seem to be.. a single 315(315 watts) =say 400watts hps,, 2 315's(630 watts)=a bit better than a single 1k hps,,, 3 315's(945 watts)= 2 600's or more like1300 watts hps..i would speculate that if you had a large area and say 6 315's they would each compare to a 600 watt hps,,, do you guys agree? i can say for absolute sure that the more 315's you run the better they seem to be,,thats why so many big grow ops are now switching from hps to cmh, they can run 1 315 over a 4'x4' area 3' above canopy spaced 4' from center to center of hoods and yield the same as running 600 watt hps's over that same area..
so a single 315 is not equal to 600 watts hps however if you run multiple 315's at some point each one will equal a 600 watt hps or more like 630 watts hps because they are capable of getting 2 grams per watt..thoughts??

You're conflating two separate issues; first, most say the 315W CMH is worth between 450-500W of HPS. That's no matter how many you're running. Second, don't mistake the advantages of distributed lighting vs high intensity light sources as an advantage exclusive to 315W lamps.

Just Finished a run under a LEC 630 in 5x5 tent. .. Excellent results. These might be denser then what I get in the main room. Look as good or a bit better then whats in the main 3.6kw flower room. I was using a total of 1575w of CDM for veg. I took the 630 out of veg for this test.,

So your 630W CMH system is two 315W CMH lights? Or how is it configured?

The SS LEC 630 is 2 315's in a single fixture.. You will like 2 Separate 315s more. Separate fixtures will cover better. Not having the ballast in the tent is also better. The 630 is a heavy SOB.

Indeed. I'm running them bare, hanging from the ceiling vertically. They work great!
