at $130 for one 600watt 10k mh that does not have a lumen rating Im left woundering if anyone has tried one of these?

I understand the science behind the uv spectrum increasing resin production, and I do believe that the lamps do just that. IMO I have gottin more trichs w/ mh added or just mh.

...but the claim that lumens has nothing to do with what your plants produce is what I do not buy. otherwise we would all be using 100watt 10k lamps
with that said these lamps are more supplimental bulbs rather than primary. so why are they so expensive??? they have low lumen outputs and thats why no one knows exactly what that number is.
There are reef tank lamps that produce the same light at 25% the cost,


**so my question is, do these sunpulse lamps work so good that they are worth the $130 per bulb?????? would reef lamps do the same thing???

everything I have just stated is just my personal opinion, thanks for any info!!!

you and me both... I know the quality will improve but Im concerned about yield, and these things are damn expensive if you end up getting like a 6.4, 3, and a 10 you're talkin a serious chunk o change.

It is not about Lumens any more.
In proffesional horticulture lumens are from prehistory.
Lumens is light you can see.
Par and Micromoles is light is plant grow light.

The standard measurements of light output have traditionally been done through the foot-candle, lumens and lux.
They quantify how humans experience the intensity of light, based on the limited sensitivity of the human eye in the yellow/green area of the spectrum (around 550 nm).
Plants however use a much wider spectrum for photosynthesis, called the PAR spectrum (Photo-synthetically Active Radiation), ranging from 400-700 nm

Human eye sensitivity versus plant sensitivity

Photosynthesis is not driven by brightness of the light according to the human eye or the energy of a photon (which varies for different colors) but purely by the number of photons in the PAR spectrum.
You need about eight photons to bind one CO2 molecule.
So to quantify potential photosynthesis it is all about the number of photons within the PAR spectrum hitting the plant.
This is expressed as Photosynthetic Photon Flux (PPF – total photons emitted from a light source per second) and Photosynthetic Photon Flux Density (PPFD – the number of photons hitting one square meter of surface per second) and it is measured in moles or micromoles (µmol) of photons.
You can measure the number of photons hitting your plant (PPFD) using a quantum meter, predicting the potential photosynthetic capacity of your light.
You can measure the total number of photons emitted by a lamp (PPF)by putting it in an Ulbricht integrating sphere
So where we used to have luminous flux in lumens, we now have PPF in µmol/s, and where we used to have illuminance (light indicent on a surface) in lux, we now have PPFD in µmol/m2/s
Lamps with high lumens output are not necessary high par output lamps: some lamps with lower lumens output have higher micromole output.
Another important issue is of course the spectrum of a lamp. Micromoles alone is not enough - or blue and red LEDs would have worked

Thanks guys,

Doc, I appriciate the info, If I understand what your saying, basically lumens mean nothing to a plant?
Its the Photons that matter, ok.
So do these lamps work as well as other grow lamps? or better?
I was told by a hydroshop owner that you can run 2 600w sunpulse lamps of 1 1000w dig. ballast? If thats true that would indicate that these lamps do not consume 600watts of power?
That would offset the high cost of the lamps, but are they only good for suplimental lighting?
thanks alot Doc, moresntoil

FWIW, I ran a 3K and a 6.4K side by side in flower and the 6.4K blew the 3K out of the water. All the plants were reaching for the 6.4, even plants directly in front of the 3K. lol

The 10K is kicking ass too. As soon as I put it in, the buds changed colors and broke out in a trichome rash. lol

Next run I'm dropping the 3K and running 2 6.4Ks during flower and 2 10Ks the last two weeks. I don't think I'll ever need a red/orange lamp again, the ladies love the blue light special. lol

cool, I would like to know how it effects your yield. I will be picking up a couple myself, most likely the 10k's to finish up what I got going now.
If your feeling up to it, a couple pics would be cool.
keep us posted, Ill do the same, later bro Moresntoil

oh- how was the stretching with the onset of flowering??

Interesting read. The splitter they make is also a fascinating idea. Using 2 - 600 watt bulbs in a 1000 watt HPS ballast. Hmmmm...

crap company .. they offer zero to nothing information about their bulb - they must have something to hide
(not to mention the fact that the osrams hqi bulbs are already close to the maximum light output with quartz technology possible - and for sure some random company wont even get close to it - cmh is better in everything. especially from serious companys who know what their doing.)

sunpulse is just some random companys (osram/philips/ge/china) bulbs marketed under a different name - and for an additional 100$ each bulb - rip off that is.

not true, these are made by a legitimate company. who makes each component I'm not sure.

the only thing they really wont tell you is what the lumen output is. thats most likely because they know most people look to see what the lumens are before buying a bulb, and their lumen output is lower than most (i think). so what they are telling us is that their spectrum is superior to others. that may be true, but do they produce the quantity of others?
I dont know, there is only one way to find out! I do believe from what I have read that the sunpulse bulbs are great at growing high grade smoke, but you may loose some quantity.

either way I am willing to give one a try, I will follow up in the months to come

In the January issue of HighTimes there is an artical that talks about SunPulse bulbs and others, along with dig ballast, and their conclusion is SunPulse lamps are superior to others. This is based on reports from Hortilux testimony that even their bulbs are not made for 20k+ hz. I do not know if HT is favoring SunPulse lamps for "other" reasons but the artical is a good read anyways, check it out.

this is all just my opinion, moresntoil

I'm not sure actually, I will get back to you on that. I know he says somewhere, but he's got that same thread posted over several forums. I'm PRETTY SURE someone asks and he tells them which Kelvin the bulb is in this thread:

https://www.opengrow.com/index.php?showtopic=37789

I'm skimming over it now and if I find it I'll post back and let you know.

Okay that was quick. First page, post #14. He says he's using a 3k bulb.

thanks for posting, thats a interesting setup he has there. everytime I see a vertical grow I start to think maybe I should give one a try.
later bro, moresntoil
