And I say you are wrong. There is much more to light than just lumens. Look at the spectrum again
So for it is performing as well as a 600 hps. I am telling you folks. This bulb is the real deal. And the lumen rating on most bulbs is meaqsured in the green spectrum, where most bulbs produce the most light. But light a plant really cannot use. PAR rating is the true measure of a bulb. EDIT: I am doing some clones, a few under 600 Eye Hortilux hps. And a few Under a 400 CMH. Proof will be in the pudding a few months from now.timeismoney1

So cowboy you saying this will be a good bulb for flowering?

When it comes down to lighting. Stop looking at lumens and color temps. Look at spectrums and PAR ratings. For example. I think a 600 Eye Hortilux hps is only like 88,000 advertised lumens. A cheapo Grow Bright 600 hps advertises like 95,000 lumens. Which bulb would you rather use?EDIT: the eye hortilux of course.

I think it is going to be a super bulb for flowering. I am just getting started with it, but it vegged wonderfully. And I am expecting even better results for flowering. It has a solid orange/yellow spectrum for good bud development. And enough blue/violet for great resin production. And the Kudos just keep coming from the folks that have been using them for awhile.

Ydah yellow red are is good. Blue is good.
Green is really high but green has no effect on plants correct?

Very little, if any. And most bulbs, of any type, are usually high in the green spectrum. Thats why lumens are rated from the green spectrum. Google PAR ratings, light spectrum ect... I bet if you do a few days of research and reading your entire viewpoint on lighting will change.

I still think cmh wont be goid in flowering. Its decent in red yellow but dont plants need more uvb?

Look at the spectrum again. The CMH blows a standard HPS away in the Cooler temps. Like I said. Spend a few days doing some research on lighting. So many focus on soil and nutes and put lighting on the back burner. Fact is the best soil and premium nutes are worthless unless the plant has the light needed to process these things. In my mind, light is the number one key in a successful and carefree grow. As much as possible that is. I mean we all have issues.

Yes i see that. It doesnt blow the mh away though in cooler colors. Its doesnt blow the hps away in warm colors.
Its a mix between the two. Hm.

Gee, what do you think the sun is? Its a mix, balanced spectrum. Lighting an indoor garden is an art. And often overlooked. There is so much hype out there. Big bud this, super grow that. An amazing 195,000 lumens. DO NOT buy into the hype. Its endless. What I strive for is a good balance down the middle. And enhance either way a bit depending on the growth phase. And remember. The sun has been around for billions of years. And it still has not completely figured it out. It often has rages and has outbursts from time too time. Approx. an 11 year cycle that is. And guess what folks. Its wake up time for the sun, wonder what this round will bring?
