    Understanding DLI

    Of course you can. PPFD and DLI are basically the same with the difference that PPFD is an instantaneous measure(each second) while DLI is a cumulative measure(over a period of time). So 12Mol/m²/day means that at the top of your plants they are going to receive around 185umol/s/m² doesn't...

    DiY LEDs - How to Power Them

    Assuming that you haven't touched the built in potentiometer there will be no problem at all with the dimming range, adding more COBs you will see a little drop in the power output as each COB will require less voltage.

    Dimming diy leds

    A 0-10v dimmer is in simple terms a variable power supply (0 to 10v AC-DC or DC-DC), if you measure the voltage across its terminals in the one you have you won't be able to measure anything cause it is not a power supply. The point when using the 3 in 1 dimming function is to drop the voltage...

    Dimming diy leds

    They call it a potentiometer because it is a potentiometer and actually none of those that you linked are 0-10v dimmers.

    LED fixtures with added IR?

    Your own body radiates IR, actually every object with a temperature above absolute zero(-273.15°C) radiates IR. That being said, even an ice cube can produce it.

    Meanwell HLG-240H-2100A On/Off Switch

    OP don't use that switch, first you are exceeding the ratings for which the switch was designed, normally an AC switch have a rating of 1/10 or even 1/20 for DC voltage. The reason for this is the arc produced when you switch off. For DC the arc is greater than AC, so the switch must be able to...

    DIY with Quantum Boards

    The graph is the JIS Color Rendering Index chart. R values are the colors and the 0-100 scale represents how accurately the light renders those colors compared to the referenced light source.
