How many LED per 23" long heat sink

[unbreakable]

how many LED would fit on a 4.25" x 23" Aluminum Heat Sink that you sell on your website?


Thanks!

We drill and tap that heatsink for either 24 or 36 LEDs, so I'd say the max would be 36 but obviously you can put much less if you want. You'll want to put a fan on the heatsink as well for some active cooling.
