    Led question is this normal

    I had that problem with countless timers on so much equipment i hated throwing away any of them, so i started using relays. The relay will completly disconnect all electricity from the circuit. I use digital on everthing with a relay they make 220 and 110v relays. No voltage leaks, can use your...

    DiY LEDs - How to Power Them

    In the driver or COB? I would think the driver would be the same, but i do believe you are correct in the loss of efficiency on the Vero 18, but that will be regained in HVAC savings.

    DiY LEDs - How to Power Them

    I would like to power two Vero 18 off one 32-34v 1750ma Driver. I know i will need resistors inline of each COB. I have looked through some books and came up with this. I would like to see each 18 at 700ma-850ma. Resistor needed=Voltage Supply - Vf of LED/Total of desired supply...

    BTW the amount of light compared to the six hundred MH it replaced the LED is much more brighter light, that is an eye measurement so take it for what its worth.

    IF you are new to LED and want help choosing what to buy, POST HERE!

    The Vf makes a lot more sense.The VF will help determine how many can be run on a string? So if I was looking for leds for those free drives to run, I would be looking for something in the 1amp and with a cumulative VF of no more than 25 volts?
