Lighting Ceramic Metal Halide

[81camaro]

There is no interference, no hum, no noise, and low heat. The technology for LEC was developed in Hollywood to be used as camera friendly lighting and has been around a long time actually.

I hears about these on the Adam Dunn show are they were loving them

Thanks Man

Dunno if you are familiar with the GN HS1 LED, if you are, how would you rate the 2 lights against each other on a per watt basis? This is a tricky question I know. The way I figure it, to cover a 150x270(5'x9') area I would need 6 x CMH 315 for a total of app. 2100 W and 12 x HS1 for 900 W, costing £3000 and £4500 or so respectively.... Hmmmm.... Guess the HS1 configuration is still ahead by a margin....

l got the impression that it is the Philips CMH 315 bulb that makes a real difference in LEC, could be wrong there!

Yup, very natural looking healthy girls basking in the sun you got, do you buy the argument that they get old faster and gain more fat on the side bones with the LEC 315 than other lights?

I've seen that GS1 in Tang's grows. It's amazing. But I don't have 20 inches to canopy, which is his recommendation. more like 15 and getting closer every day. I'd burn everything, I'm sure. lol. But LED was considered, and was actually the direction I was going. I flowered a blue kush under some household 16w LED lights and i'll use em in the corners to supplement as soon I can rig something up. The 3x3 square footprint fit my box too well, as can be seen.

315w CDM is the best grow light there is. I've used them for a couple of years now. Maybe in the future LEDs might surpass it, but they're not there yet.

If your going to make a claim like that, we need data to back it up. CDM is a nice technology, but its in a field thats at the end of its development life. LED is is still in its infancy, yet it has already surpass all MH/HPS, Plasma, etc. I was a skeptic but When I see what has been accomplished with Grow Northern HS1, a light that runs on about 100 watts, prrof is out there that LED is taking over because its superior. I check out a lot of light tests on youtube, and seen some nice grows with CMH for sure, none that I would call superior

Hope I did that right. I think it speaks for itself. This more than anything sold me.

For me the height to canopy was the limiting factor. It was a personal decision to minimize input resources. This is has to be viewed from the perspective of a 1-2 full sized plant grow intended to keep me in smoke, not cash, lol. There are reports of 3 of these being used over a 4x8 and producing good results if commercial is a concern.
As to LED, sure they are expensive, but what's not to like. I believe there greatest advantage is the ability to custom tune or shape the spectral output. A bigger unit is available, the LEC 630, which is really two 315s in a single reflector.

The best comparison in output is a 400watt plasma or an aircooled 600. And both block UV because they are behind glass. If I can do anything like Tangs got going on under his GS1, well I'd be real happy. My ultimate goal is to lay down some long tall slow landrace Thai stick. So I want that UV. Probably toss in some reptile lights last few weeks to up the UVB.
