I am guessing they stuck with the same board size and heatsinks so their products are modular. Everyone would be calling them Apple if you had to completely upgrade every component each generation. You already have to potentially upgrade drivers to use the new boards, if they also needed new heatsinks adoption would be much slower. But your idea definitely sounds cool!

Its just that they are not working for everyone as a bare bulb SE replacement. Whilst the QB knock off specialists are offering the spread in diodes or split option modularity along with the option of your heatsinking. You can go minimal, max or regular thermal mngmt.
And im glad someone finally said it: Thermal paste or interface. What the heck ever made people look past that?
Twice as many diodes & over 600w while being the same size?
Sounds like 1000/1200w DE, Drop i replacement. (With No diffusion option @Stephenj37826) oh boy!
So Stephen, in your opinion or math, is this Diablo an L/70 product based on the manufacturer design?
Does this mean were up to a 36" hangin height now? If people think they get twice the efficiency by dimming to 50% that's not the case. The #'s are marginal. But that will increase the longevity.

The Rspecs(and the Bspecs apparently) are for sure 3500k diodes.

Man, I hadn't known this until now as well. I could have sworn they used 3000K + 660nnm red. I guess just one more thing in the past few days I've been schooled on to add to the list.
One thing I don't like is the blue curve on spectrum, from 3500k to 4000k, is such a jump. At 4000k, you're committing to Blue hittin' the 100% mark. Not even mentioning from 3-4000k. People always see 5000k as the veg cct, when in reality, you don't get much MORE blue (besides a bit wider of a curve), but only less and LESS red.
This is why when people say, as you stated @hybridway2, that they swear flowering with 4000k, I don't get it.
For veg though, I really do think it's everything you need.

See how you had to edit out the LOL you put once you googeld and tasted your foot in your mouth?
Why do you attempt to speak down on people when you're the one that is so incorrect it's laughable?

It is that easy. It's also that easy to find out that it is that easy. But you choose to attempt to talk down to people when you are in the wrong in information and your attitude.

CRI= Color rendering index.
The reason why a white LED falls into 70cri or 80cri is almost purely in it's R9 values. R9= the red portion of the color rendering scale. So how do you get a low R9 up....by adding red.

See man, you missed the whole point because you're to focused on defending the same company i am constantly trying to help. Its the defensive wall some of you have built in your head. It stops you from learning anything more the HLG offers you. I'm sorry dude but thats what you're showing here.
Maybe you can achieve a 90 cri just adding a touch of 660. Never saw that before as the "Cyan Gap" is very pronounced & their's No 730nm. So idk man. But if it says it is the. It must be true, so my bad.
Cross the B-Spec with the R-Spec (which was 3k) & add 730, then youll have true 95+cri board. Add 400-430 & have a 99cri board.
Again, Now How did I talk down to anyone? And who the heck are you really? Sock boy.
Quote one thing i said that's incorrect pls?
Then check yourself.

I believe HLG steve stated somewhere on the gml show that they went with 4000k/more blue in order to help the stomata opening and help with transpiration since the new diablo is very intense.

Yeah, the 4k slightly bumps the "Cyan Gap".
R-SPEC in 35k x B-Spec in 35k + 730 with bigger, adjustable boards at 600w capability is an HLG , QB I would buy.
With a diffusion option.

The Rspecs have ALWAYS been 3500k diode's as far as I have ever seen. I bought my two shortly after their first release.

That being said, I still prefer vegging under the v2 4k's. The plants just look and respond better in veg with that spectrum. The rspec's work fine, with just a little taller internode spacing, but the 4k's are just better when it comes to veg. I haven't personally tried the Bspecs yet/though.

And how big are your plants before flip, how long do you have to veg for?

Doesn't really matter? Lately I've been vegging for two months or so, 1-3ft tall plants. In my opinion and experience, yeah, they just look and respond better under the plain 4k's than the Rspecs. Takes a few days to switch over to the rspec before they start to take off again, like the leaves have to adjust to the increased red. Flowering has been fantastic with the rspec's though.

So I get that, but could you explain in terms I can understand, so my example is decibels so with every 10 increase in decibels you get 10x the increase in sound. So when it comes to umol what percentage of increase in performance would occur?
Click to expand...
The constant would be the maximum amount of light you can apply to your plant canopy. Any increase in umoles should be seen as a reduction in power consumption to achieve that output :peace:

Thanks, i kind of assumed that. I guess what i was getting at is a % increase of how much each 1 umol, .1 umol .01 umol was worth.

So using a 4K diode that renders @80cri + red, then setting the sphere up to read a 35K source and having the unit land @ 92 cri seems like moving the goal posts a little?

Hey @hybridway2 have you had time to peruse the QB 648+ datasheet yet?

Section 2 (characteristics) a) (basic information) rated lifetime is >50,000 hours
and under "Remark" "L70B50" is shown.

The color spectrum curves are proportionate to the overall output, so yes you do get more blue in a 5k unit than you do in a 4k unit. Don't let an illusion fool you.

Have horticultural lighting companies come up with a set of standards for reporting spectral quality, yet. Thought they were trying to in USA, sure I read something but can't remember where?

Need to come up with something that is easy for all to comprehend. Like Nutrition Facts labels on foodstuffs. Sometimes feel that spectrum curves, Kelvin and CRI do not give a horticulturally oriented indication of values related to spectrum.

No dog in this race. Only providing the info.
I generally recommend 90 cri white diodes but not for the cri in itself, plants wont care about what things look like to our eyes, but i do like the extra red and far red. To me it just seems simpler to have the extra red baked into the white spectrum rather than having a few red diodes turn on for flower. Or-gros sbs seems to confirm this. If i had to build a diablo-like light id go for 2700k 90 cri white and then a wide violet/uv/480nm on a separate channel.
