CXB spectrum vs output

What current are you guys running for the readings?
Hi Greengenes
to be honest these were tested on our workshop regulated Power Supply and set at 36 Volts and I did not note current settings at the time, however you can extrapolate from Cree volt /current graph, suffice to say these would have been at a higher current than you guys probably run them at as you seem to underdrive to gain efficiency. If you like I can retest these at the preferred run characteristics and produce the results here, let me know

All good man. I meant to say or voltage too...I figured you guys were using a bench supply. They are VERY useful and the current differences are minimal and should not even be thought about really. My graph are from a spectrometer too, at 1.4a. Energy weighted though.

@led2076 that is great to hear. I look forward to sending some of my dollars over to Cutter. Our money is the same color as everyone else's and its really nice when a company comes out and supports what we are trying to do here

(*unlike some companies that I have contacted for a RIU discount code. that have sold out of a certain profile , after a certain person / people released some videos recommending their product)
cough cough 5.886...

LOL I requested a promo code from the last year to share with lampbuilders and they said aluminum prices had gone up. Except...
alum prices.png

But in the other hand, I am grateful they do business with us at all and I love their products, so I try to wait for the 10% off promos.

their like " wait it was the electric prices not AL prices that went up " ......................eye roll
they got us by the short hairs ,

off topic but relevant ...you can save bucks using scrap heatsinks. I mounted my passive 3590's on something like this:




It saved a huge chunk vs heatsinks usa

19-5/8" X 12" X 2-1/4" about 70$ shipped in USA. this profile weighs about 1 pound per inch

That's what I was told! And to top it off they are having some kind of problem with their extruder. They said they will hopefully get it operational by the 8th.

Guys
We use a Asenstek Spectrometer, the product is supported with an Grow Light App that produces the above details, you may note on our site we have produced the same chart for each CXB3590 we are selling to you guys. Happy to provide more info if required
Cheers
Mark
Mark can you put up the same information for CXB3070 BB 3500K

Would really like to know the figures for it compared to the CXB 3590

will do. I will use test bench supply and and new Power Supplies at 1400ma to give a more useful chart for you guys. I note on 3590 we tested at 1400ma all chips are putting out 500+umoles, so our original post of 900+umoles was clearly at full drive curent

I want to purchase 3590's CXB 90 CRI 3000K cobs, how could I drive the lights to 500 W per 4 cobs? What drivers are stable enough to do this? Im planning to use CPU coolers with fans on each cob because it will be cheaper than buying 36" heatsinks from HeatsinkUSA because of the duty fees and currency exchange.
