Bridgelux thrive spd

[Horst]

Hey guys

I got testing for the thrive. Led-tech.de has integrated it in their spd tool.
Only the 3500k but I think I understood something.

Look at the spd chart at 2100ma, 1400ma, 700ma and 350ma (14 leds parallel and 7 seriell in this 98 led Strip)

I think the different spd Charts comes from different currents. Especially around 480nm it’s very different at high and low currents.
In the datasheet for the thrive eb strips it’s not clear if the current is at 700ma or 960ma for the chart.

Last question open for me, is why there are thrive with 125 lpw and some with 145 lpw.
Any ideas about that?

I need to have a good look at the latest data sheets for the thrive.
Originally they had a 420nm pump and used blue phosphor to increase the cyan
From the look of the spd you have shown they are using a dual pump 450nm/470nm with phosphor

Using dual pump you will increase the LPW because there is not as much phosphor needed to achieve a similar spectrum because the blue phosphor isn't required
LPW and m/joule becomes a little tricky with these spectrums to work out what is best. My personal opinion when it comes to growing is to use the spd with the 420nm pump.

It’s the 3500k. I think 5700k and 6500k have different pumps.
That’s why am only interested in 5700k and 6500k anyway.

Do u know why these are different?

I think the inconsistency in the LEDTECH data shows the same concerns I have with testing the chips, CRI is inconsistent and efficacy is all over the place. Right now imho these dont rate in comparsion to Cree, Lumileds or Nichia

@Welight

Do u think the inconsistency is a problem over time too? For me all what counts with the thrive is the peak at 480-485nm.
I have no problem at all running them with 350-450ma with even higher peak then. But do u think they will shift and change over time a lot?

And the efficiency.....these strips from led-tech are at 125 lpw (second datasheet last post) and the eb strips are at 145 lpw (first).
I would combine 5700k thrive with 4000k cri90 2:1 and would get around 160 lpw without cyan gap and a little at 430-440nm. For flower same power in 2700k cri90 in addition.
But If the peak is 15nm elsewhere or disappeared like in tekkniks measurements than nothing work out and all would just be a waste of time, resources and money.

Maybe it’s a better choice to take the older optisolis with less efficiency....they are better at 405-420nm anyway.
I did look at cutter, do u have pure optisolis strips? Didn’t find some. I wanna mix it up myself

we do but they are the most expensive strips

Yh expensive is right.....boah. They are quite old, why are they so expensive?

But am wondering about another point too. 4000 lm at 560ma/48V. That is 148,8 lpw....really?

U know anything about the two different thrive?

Is there any more info on this? Are the new Thrives really crap? I'm looking at the Gen 3 2700/5000k versions.

Thanks

[nomadsoul]

I guess more specifically, is the Spectrum better for growing on the 80 CRI Vesta Gen 3's, or the Thrive version? There a massive difference in efficiency, but I'm ok taking the hit if the spectrum is worth it. Which emitters/pumps these new models use and how that effects growing is a little beyond my knowledge at this point.

I don't think the Thrive has enough far red or UV for me to not have to add supplementary diodes if that's what I'm after, correct ?
