    Matching Drivers and COBs

    I have 4 2700K CXB3590 CB bin. At 20 degree Celsius and 1400mA the forward voltage of this 4 COBs is 139.64 Volts. The HLG-185H-C1400B gives 143V/1400mA/200.2W maximum. This looks like a perfect driver to me (97.65% of maximum load). Or are those 4 COBs at 1400mA too much for this driver. I...

    My driver is hurting me. It fell on my too.

    Matching Drivers and COBs

    I am planning to make my own voltage/ampère/wattage meter (arduino based) in each light fixture and make them able to daisychain with each other so that is is possible to run 4096 fixtures on 1 controller. Temperature of the COBs, voltage and current are lohged. I go to bed now. It is 2:43 here.

    Your spreadsheet tells that a 3500K CD bin 36V CXB3590 at 50 degree Celsius, +-33V and 64.01% efficiency consumes 22.9 watts and gives 2.98 umol per watt to the plants. This spreadsheet is from supra and i give it 25 cents. I am new to leds and lightning. Just my 2 cents, but i swear that i...

    Growing green beans, i search the data right now........ Okay... It is a 150.5 watt 700mA maximum driver. I assume that a 700mA CXB3590 consumes about 33V+-. so 33*6*0.7 (V*amount off cobs*A) = 138.6 watts. That looks like a perfect match for that driver. The HLG-120H-C700 is rated/stated as...

    That is great. I lost my multimeter and got a buy new one. I got 5 cxb3590 on a HLG-185H-C1050 constant current model B with a 10K resistor on the dimming leads and my 5 magic lights are very bright at 10% and thus <20 watts if the driver really dims to 10%. If this is true i will replace every...

    With the HLG-240H-42 that would be 240/6=40. 40 watts per cob maximum.

    Matching Drivers and COBs

    The HLG driver data sheets are very clear about voltage and ampère, constant current or constant voltage. If i look at the datasheeys for the HLG-40H-36B i see that the ampères are adjustable from 0.67 to 1.12A (for the a model only). If i look further on the datasheet i see dimming properties...

    No i am going to use the HLG-40H-36b for one cob. That is max 36V 40W.

    Matching Drivers and COBs

    Th I am going to use that driver for 1 COB at 35V and 1.12A (and as low as i can get with that dimming) . I could run 2 COBs at 35V and .56A but that is only 20 watts per COB.

    This is very interesting. This article describes why it is a good thing to almost max out the HLG- B series constant voltage drivers. http://www.adminstrumentengineering.com.au/instrument-engineering-news/dimming-with-the-mean-well-hlg-and-lpf-d-led-drivers

    Matching Drivers and COBs

    Another question... Are the HLG- series B version drivers dimmable to 10%, so that a 200watt driver dimmed to 10% only give 20watt?

    Matching Drivers and COBs

    Hello. I have question.... I want to drive one cxb3590 with one HLG-40H-36B 36V 1.12A max. A CXB3590 at 1.12A does not take 36V butt less i thought. This setup will almost max out the driver. Is this a reliable setup?

    I have a spectrabox. It is rated 180 watt but i never measured How Many watts it really was. The spectrabox was in a 2x2x5 tent. I ran 4 cycles with it and i grown weed with it. This was the first time i grow weed. The best i made out of one cycle was 92grams dry weed. Now the lenses above the...

    Work out heat sink requirement?

    The heatsink mentioned in my earlieër post is predrilled for Cree CXB3590. If u want an undrilled heatsink i can suggest https://m.alibaba.com/product/60244347010/OEM-Passive-Pin-Fin-Heat-Sink.html?spm=a2706.7835515.1998800312.25.Ds1fFi Ultracheap!

    Work out heat sink requirement?

    If you need a lot of heatsinks i suggest Vicky Song or Jerry Meng from kingbrite on Alibaba. The heatsinks are cheap ($9.00) but the shipping to the Netherlands is $40.00. They will put a little price on the package for customs (just ask)...
