    These bolt length ways onto my ISH 288.



    Just got to get them fitted now.
    Have you got the spec sheets for the leds mate?

    Far red is less visible as you are moving into infra red / heat

    Just out of interest how much blue are you using? Some say optimum is as low as 5% of total lighting as its very high energy and just whizzes through the leaves without doing much?

    Hey Gardo

    Below is what I got from the Chinese sales team.

    I am using the Meanwell PLM-40-1050 driver on the far red and the Meanwell PCD 40-350B for the 460 and 660nm.

    The Meanwell PLM-40-1050 could not run the 460nm in series. That is why I wondered if I should go and purchase another PCD 40-350B for the far red? I will try it out shortly!

    Edit : Tested the far reds using the 40-350B - much better. Bah - 3 unecessary drivers and gotta but another :-(

    460

    CREE XPE Royal Blue 460nm 11pcs in series
    Dimension: L560mm X W30mm, thickness 1.6mm.
    Voltage: 34V-43V at 350mA; 38.5V at 1050mA;
    Suggest driver APC-25-350, $8.5usd/pcs


    730

    CREE XPE Far red 730nm 11pcs in series
    Dimension: L560mm X W30mm, thickness 1.6mm.
    Voltage: 21V-26.4V at 350mA; 23V at 700mA; 24.8V at 1050mA;
    Suggest driver APC-25-700, $8.5usd/pcs


    660nm

    CREE XPE Photo red 660nm 11pcs in series
    Dimension: L560mm X W30mm, thickness 1.6mm.
    Voltage: 23V-27.5V at 350mA; 25.3V at 700mA; 27.5V at 1050mA;
    Suggest driver APC-25-700, $8.5usd/pcs

    They are bolted onto the ISH 288 which I think is 265W. I did not opt for dimmable ballasts. Perhaps I should have done.

    I can test the draw of each pair on the wall if you like?

    Looks like roughly 10%

    Assuming these are the real mccoys then heres the manufacturers data per led so we can select best driver based on this


    So we need a driver that can source 700ma ( absolute max 1000ma) at 11 x 3.1-3.9 volts so 34 to 43 volts

    Let me have a look which can do it and come back with recommendation

    Edit: and you have 2 strips so 68 to 86 volts

    Many thanks! I have dots in front of my eyes!!

    I have struggled pairing driver and strip!

    I am concerned I am overdriving them!

    Heres how sensitive they are to voltage

    Tiny increase in voltage gives near exponential increase in current. This is why i never recommend constant voltage drivers as leds can fry

    Gold standard driver for 2 royal blue strips will be HLG60H-700B - fully dimmable

    This is with the 2 strips connected in series and will never blow the leds no matter the setting. There are other drivers out there at lower budgets of course

    I think I will go gold standard and get the best drivers for the job. I have one HLG60-700B currently running my other set of 660nms.

    Would they also work for the other strips? May as well bite the bullet. 5 duff drivers! Should have asked here first !!! Saved me a fortune! All for a few extra watts of light!

    They give you the specs for each board. If you could get like a 45/46v driver 350mA you could probably run one blue the same as two red in series. If you are wiring the boards in series that means you need both voltages of the boards. Parallel you need both amps.

    Happy to help whenever.

    That driver is bespoke to 2 royal blue strips .

    Always best to plan out whole project and allow for future development and expansion if you like

    You can combine almost any strips onto a single driver if you like a run them in series. Cant really run far red with whites and blues though, well you can but the whites and blues would be dimmed.

    Meanwell HLG are the best drivers imo. Some led supplier cut costs and dont use these but then they wont deliver the efficiency they claim. No point spanking watts by heating up a cheap driver

    Can I be cheeky and ask what I should use for the 660nm and 730 as well. Ideally gold standatd dimmable to give me full control.

    Many thanks dude!

    How many strips of each and is it 11 per strip?

    (Assuming these are real of course)
