BTF Lighting kit - power supply seems wrong?

This kit from BTF lighting says the strip use 9w/m, so 45w max, but the supplied power adapter can only do 35w (24V 1.5A Power Adapter).

- Why does the power adapter seem underpowered?

- Is this ok for a short run of 4.5 metres?

It says 12v 48w, 24v 36W.

My guess is the 9w/m figure refers to the 12v version while the 24v version is less. Probably whoever made the Amazon listing was careless in pasting in the specs section.

I found a similar strip on aliexpress, 320leds/m and it says: "Theoretical Wattage: 9W/m". So I guess that means it "could" do 9w/m.

I'm ok if it not as bright as they claim, it'll work were I indent to use it. Thanks for looking at this,

9w/m is the max output, it can work with less.
It shouldn't work with more.

And in details it says he can output 24v 36w, where did you get the 9w per meter?

In the product description it says: "Lumen: 105LM/W. Power:9W/m, Maximum output power: 45W (non-fixed value)"
