2xCXB2530 LED but which driver?

looking to buy this tonight already have a huge heat sink off an old ibm comp. just wonder how exactly do i calculate what drivers i will need. long time listener first time caller much appreciated

It depends on what current you run them at. 2 Is a hard number to work with without using individual drivers, which generally means lower driver efficiency and more wiring complexity.

Something like HLG-120H-C500 is the smallest 94% efficient driver I know of that would allow you to run 8 of them in series at 500mA...

HLG-120H-C700 is is 94% efficient at 700ma and supports 6 in series.

You could get HLG-80H-C700 and run 3 in series at 700mA 91.5% efficient driver

You could get HLG-60H-C700 and run 2 in series at 700mA.. 90.5% efficient driver. There's your 2, but it'd be at 700mA, and slightly less efficient driver.

thanks going to go with getting the 6 instead. i appreciate the help alot man!

According to @SupraSPL

CXB2350 3K U2 @ .5A = 17.42W -> 49.1% -> $2.82/PAR W
CXB2530 3K U2 @ .8A = 28.8W -> 44.2% -> $1.90/PAR W (test current)

They are both very good options, and if you drive at 700mA now, you could always get 2 more later and upgrade to 500mA, and use the 700mA driver for something else.

Make sure you get the U2 bin if you're getting 3000k 80cri, or T2 bin if it's 90cri. (top bins)
