Sorry, I'm leapfrogging posts.

If I run blues @ 15.1V:

1.2A x 15.1V= 18.12W each blue

3 x 18.12 = 54.36W

54.36W x 1.3 = 70.67W

Is that how you figure it? Is the PLN 60-15 just marginal to drive 3 blues, or are they just being real conservative?

They are more likely to run at 12.6V or so at 1.2A.
You'll be lucky to get close to 15W. ea.
Since you are not going to get more than 45W. into 3 blue leds, the PLN60-15 will be just peachy.

45W. X 1.3 = 58.5W.

Next time I score some surplus cash, I'm gettin' acouple of those Meanwells.

Just beginning to get vertical.
