Under powered for a 48" LED
That power supply is rated 12W
You actually didn't say what size light you have.
Anyways power supply can be rated higher, amp or Watt rating.
(Voltage NEEDS to be a match) but lower doesn't work.
Best case lights will be dimmer than with the correct wattage, worst case you burn out the power supply eventually.
A bit confused by why the mA rating is so low:
32/24 = 1.33A for a 24
2.45A for a 48-60
Light will only draw what it needs so like a 3A 24V power supply can be used for any of them.
@ 15-24 light I suppose it's possible.. Still seems low though at 12W.
