Ac/dc adapter replacement

Hi I’m looking for a power supply for my aquatic life Halo light.
Would this one work?
Original: 33V~2.7amps (photo with pink tint)

You need one that’s 33v and >2.7a

Ok I thought so. Seems hard to find a 33v power supply locally.

33V is pretty unusual, you'll find lots of 36V supplies. This may work, but I can't vouch for it. Devices should happily take +/- 10V, but you never know.

Some of the meanwell series (HLG-) come with voltage adjustable versions, where you can buy the 36V variant and trim it down to 33V.

Hmmm ..maybe
If the power supply runs switching drivers the 33v is sort of optional.
Could be fine with a voltage >33v

If the diodes are run in constant voltage strings that is a different story
Or if they use linear drivers or the driver ic's have voltage restrictions.
Point is there are " maybes"

As noted 33v is pretty odd and not enough info to really judge if it is an absolute

Anyways a Meanwell lrs-100-36 ($17.09) trim-able down to 32.4v (33 in this case) should be fine.
2.8A 36v 100w 32.4-39.6v 3yr warranty.
Cage vs brick ps.
