Difference between Mean Well drivers

I have an small 18"x18" area and I plan build my first led light using 280mm EB series 3500K, at 350ma.

Could someone explain the differences between the Mean Well LPC-100-350, HLG-60H-C350A, and the ELG-100-C350A drivers besides the HLG-60H-C350A being only 70watt. Would any of these work to power 8 EBs in series?

Thanks

The LPC-100-350 is not dimable and has a little bit lower efficiency but are the cheapest option. The ELG-100-c350A is only 70 watts when hooked up to 110 voltage and 100 watts when hooked to 220 volts. The HLG-60H-c350A is the best fit it has a max voltage of 200 volts the strips you want to use are 22.1 volts ...so 8 x 22.1 = 176.8 volts 176.8 x .350 = 61.88 watts is what the total of all strips would run at. All those drivers would power 8 of those strips But I would go with dimable for sure.

DSC_0630.JPG DSC_0631.JPG On the driver subject, I made a light with 16 of the 2 ft eb strips. Each pair of 8 is powered by a Hlg240h-24a.

I made a new 16 strip light powered by a hlg 480h 24a. But my new light dims all the way down to 0% my old light only dims to 50%.

My question is... Is there a difference in drivers or do I have too many lights on the new 480w driver?

Pretty strange the A drivers are not supposed to dim below 50% might want to contact Meanwell

I'm mixing 3k and 5k but I did with the smaller drivers as well.

Maybe with he bigger driver powering the full 16 strips there's some voltage drop . Maybe I need to take away two strips?

You are running in parallel so if you take two away you will just get 1.42 amps per a strip rather then 1.25 amps running 16 strips.

very nice, you newbies got it so good nowadays. You wouldn't believe the crap we started with back in the day.
About your question, if it works and didn't catch fire you are good. THe softer you run it the better it is

Not necessarily. That only occurs if the driver is operating in constant current mode.

Yeah nothing is getting hot, and the lux meter from my phone is reading an even light spread no hot spots so....

I could rewire like this picture if need be.
