yes, and some golden logo could turn to silver

Which print color you refering to?

So, will you replace HPS by Ceramic HPS?

8-)HIGH CRI HPS is not a new tech

Hi dude, dont be sad. The fresh new bulb could be like this, the factory do ignition test before ship them out. The ignition test is like its name, to see if this bulb can be light up or not. It is a standard QC control. Why this one dark the two sides of arc tube? Because when ignition test...

Not yet for sale, but i know where to get them, we can startup a conversation talk about this.

Yes, one ballast drive both CMH DE and HPS DE, and you just need to switch the bulb. But in order to do that, CMH1000WDE must run with 1000W set, cannnot afford over power use like HPS1000WDE.

Nanolux 1000WDECMH need to run to low frequency ballast, right? I guess everyone is looking for CMH1000WDE high frequency version, that can switching HPS DE and CMH DE in same fixture.

Hi Ronfro! just realized you put a link on "guys" haha, much appreciated!

Yes, but to block UV-C, it will vastly reduce UV-B, UV-A transmittance. In the other hand, to increase UV-B and A, it will allow certain amount of UV-C come through the glass. I have some prototype 315 that as same as Philips but can give more UV B and A, also little big UVC.

I think Philips CMH blocks UV, it will be great on THC if it is not UV blocked.

Whole stage with CMH, seems promising on flavor:weed:. Thank you man.

Dual spectrum is a fake idea 8-)

Have you tried Grower's Choice CMH? Many smaller brands out there, idk if worth to try.

Hey, thx for the detail. Since Philips is focusing on its LED, i think other brands CMH will take over its place. What do you expect more on CMH? PAR? or better spectrum?

If CMH has strong PAR output as HPS on red light also good on blue light, can it replaces HPS on flowering stage?

ive heard EYE hortilux CMH315 is the best, cuz it has more UV than Philips

haha, im not a pro of grow. Just wondering if some well-know ppl or labs have done CMH lights test between brands. Interested in which brand is good, also i have something new that need ppl to test :D

Hi Everyone, I have some different brands of CMH lights, interested to see the which one is the best. Does anyone know if there is any professional labs or person can do contrast test to give real time grow results? Million thx!
