that would be much appreciated.Same intensity and spectrum as sunlight IS bullshit. The true 10k does have a SA just do a google images search. It's on the packaging.
I have done a SA for the Hamilton Technology 6k and the SunPulse 6k and the Hamilton Technology 6k is better. 6.4k or whatever.
The differences were in the amount of green and yellow vs blue. The SunPulse had a larger Green and yellow spike where as the HT had a shorter one. It's hard to explain so I can just paste the SA here for you when I get home!
I can paste all the SA from any lamp I have that way you can judge for yourself.
I have been stating over and over that sunpulse was merely manipulating the green and yellow portions to achieve the K temps.... doesn't change ANYTHING as far as plants goSame intensity and spectrum as sunlight IS bullshit.

already spent the cash on some very lightly used ones, 25 bux a pop for 1000w and 600w 10k and 3k so I'm not out much, the solis-tek 4k I bought new at the grow expo for 60 bux . bought 2 lightly used 1kw hortilux blue for 25 bux a pop too. used here doesn't bring much. so how would you say the spectrum of the 1kw blue is if it were dimmed to 600?There's not much to worry about if you already spent the cash on Sunpulse. In the future though look at the aquarium MH they are high quality at lower price.
I've found lamps identical to Hortilux Blue at almost half the price. Iwasaki 400w is the same as Hortilux. These horticulture guys are just slapping their label on the same product and calling it horticultural when they are the same as aquarium lamps.
I've even discovered that the SA for the 1000w Hortilux blue is different than the 400w. The 1000w has a HUGE amount of energy in the 525nm green compared to the 400w.
That being said, you will get better results with 2x 400w Hortilux Blue over 1x 1000w.
they may not use quartz but they use decent glass, low iron. all they claim is that their lamps emit more uv than most mh.I have been stating over and over that sunpulse was merely manipulating the green and yellow portions to achieve the K temps.... doesn't change ANYTHING as far as plants go
Sunpulse are NOT using quartz glass formulations so their uv claims are moot
I have a Science and Art degree with a focus on Glass Art. I mixed/melted the raw materials to make the glass. I'm also a boro lamp worker and know the materials that go into the products. Boro is what is used for making the MH and HPS lights. At least they SHOULD be using boro. Maybe in China they are cheaping out and that is why some people are getting SunPulse lamps that are melting.they may not use quartz but they use decent glass, low iron.
not really if its too thin transmission would be all UV rays and the composition of the glass is the most important factor. thinness not so much.thin fragile glass just tells me that their claim of producing more UV than other mh lamps is true. it's not that the glass is cheap, I've talked to sunpulse about this. whatever the case you've made my mind up for me, I'll be running a 600 watt 3k sunpulse and a 600 watt 4k solis tek on the mover, gonna add some red with various (not kessil, i wish) led and see for myself.
I was contemplating and now you just made up my mind to supplement Kessils red in flower and blues in veg...thank youHere's the SA for Sunpulse 3k,

Here is the SA for Hamilton Technology True 10k,

And just for comparison, here is the SA for Hortilux HPS so you can compare it to the one on their packaging. This SA is more accurate,

As you can see, the Sunpulse lamp's energy focuses mainly on green and yellow and maybe a little bit of yellow-orange. Not so great for flowering although it will work especially if combined with the Kessil Red h150s, but you need at least 4 of them combined with a 1000w MH.
I like to use the Hamilton Tecnology 6.4k with the 4 Kessil h150 Reds. Here is a combined real life SA of that light source,

I can't tell you the "Kelvin" rating, as if it even matters, but if I was to guess it would probably be less than 3k. And the more Kessil red h150s you add the lower the Kelvin rating.
This is the closest in a single lamp I have found...BUT I also supplement with T5 ho and MH uvb lamps...and in the not too distant future some KessilsAnd just so everyone knows, this is what the spectrum of the Sun looks like on a sunny afternoon in the Fall. Not even possible for a MH to come ANYWHERE CLOSE to matching the Sun's spectrum. LMAO!

Those h150 kessils are not the greatest in quality for the price they ask. Make sure you find them for around $170 if you are able. They shouldn't be more than $100 each IMO.I was contemplating and now you just made up my mind to supplement Kessils red in flower and blues in veg...thank you
not pulled from the market, they just aren't making anymore, you can still get what's left.http://www.advancedtechlighting.com/cdmed18.htm]Phillips CMH 400w's have been pulled from the market.[/B] They are being replaced with CDMs whatever that is at 315w. I guess they have a slightly different spectrum, but I don't know for sure. I'm going to start using HPS again, but combined with Deep blue/Blue/Red/Deep red LED to complete the spectrum. I was doing this with MH, but I want to see if HPS does any better since they have a higher spectra absorbance rate.
