    Need help choosing drivers!!!

    The drivers are capable of running one more cob per fixture. I ordered 4 4k vero29c to build a seperate veg light but now thinking i should relocate the huge drivers on the side and mount the 4k in the middle and dim it down to 400w!! Any suggestions? Would a 2700k do better in middle then...

    Need help choosing drivers!!!

    So i decided on the hlg480-c1400b!! Now I'm wondering if the newer meanwell drivers 0-10v( dim to off) need a resistor before the potentiometer? Vs the old drivers 1-10v. I know I should add one on the pos side for full driver output but not so sure about dimming below 10%. Any info appreciated!!

    MeanWell LED Drivers: 3 in 1 Dimming Function.

    Right!! But I've also hear to put one on the negative side as well, so the driver doesn't go below 10% dimm from what meanwell states, it can cause problems!! But like I said I'm not 100%

    MeanWell LED Drivers: 3 in 1 Dimming Function.

    I'm not 100% but pretty sure. I'm still learning myself as I just got 3 hlg480-c1400b and it's dim to off and wondering if I need resistors!!

    MeanWell LED Drivers: 3 in 1 Dimming Function.

    I believe the two smaller meanwell hlg 185 and 240 do not dim below 10% meaning no resistor before the potentiometer. What I don't know is this new dim to off, is it still required to use a resistor?

    @CobKits @welight One hole falls under the metal chip but not the les!! Is this ok or what should I fill extra 4 holes with, tim, or run extra screws in and cut heads off?? Will be pushing 85 to 100 w. Dont want to ruin my veros!

    Need help choosing drivers!!!

    Ok, I just looked and they are se (poke in)version! The Se is the same spacing but only 2 holes! So after taking a quick look at my v4, the reflector holder align with se holes and use longer screws to hold it! So the cob and the reflector holder are held by the same screw!! They are ledil...

    Thanks for the Information! I'm almost 100% on getting the solder version! I have se on my timber v4 model that has a ledil reflector but haven't looked much into optics and the two you pictured above are the only ones I've seen!! What kind are you referring too that will not fit with the se?

    Need help choosing drivers!!!

    Thanks great to know! Yes I can solder, im a residential electrician and never liked when people back stabbed or poke wire in the back of devices because its gonna expand and contract and it can loose connection easier than wrapping it around the screw. So I'm still learning this voltage with...

    Yea I keep going back and forth on all 3000k or mixing some 2700k or 1700k!! It's just for flower but now that I think about it, @CobKits I also have a amare 450uvb that i run next to my other cobs and i keep the veg switch with blue light and flower switch with the cobs both on and it always...

    Need help choosing drivers!!!

    Yes I run the timber Vero 29 at 1400ma x4 the square 125mm sinks which get a little warm to the touch when at full 400w. That's why I bought these sinks as they seem to work very well, And I do have fans blowing for circulating and making strong branches. Also thought of throwing in a couple...

    Need help choosing drivers!!!

    @welight is that 300v rating for the Pico connectors or holders? And if I solder instead of using the Molex would the rating still be the Same! Just trying to decide between Vero c or Vero c se and why is the poke in version cheaper than the regular one on some sites and other sites the regular...

    Need help choosing drivers!!!

    The Se and regular vero29 both have built in holders! The Se has poke in connection and the regular has Molex plug or soder!! I know the Molex connectors are not rated to run in series. I need to know the voltage rating of the holder of the regular vero29 c if using the solder connections!
