Aquarium LED lighting question

Hi all! I own an aquarium and recently purchased a new LED light only to realize that I also needed to buy the transformer as well. My old LED light has a 24 V transformer, and I plugged the new light into that and it worked just fine. Being as I know nothing about electric/lighting, I do have one concern.

-The old light (9 W LED) says 24 V = 9 W where it connects to the transformer
-The new light is a 23 W LED, and the company instructs you to purchase a 24V 60 W transformer for it. I've provided a link below.

My question is, is having the 23 W plugged into the 24 V transformer rated for 9 W safe? Am I going to come home to a burned down apartment from an electrical short/overheating of the transformer? The transformer gets pretty hot, but it did with the older light as well.

Thank you!

24 volts doesn't equal 9 watts. Watts is the product of amperage times voltage so that is nonsensical. You need to look on the old transformer for the amps (a) or milliamps (ma). If the transform isn't to hot to put your hand on and slowly count to ten you should be fine.

Is it safe...... maybe. Is it recommended..... no. I'd use the larger transformer.

I'm kind of surprised a new light didn't automatically come with a power supply.
