Transformer requirement for LED lights

Thanks for the reply Mike. The output is 1500 ma and 13.5v. So according your calculation (1.5 x 13.5) that would be a max power of 20.25 watts. Is that right? But that's still a bit shy of the 22 watts needed. My dual ramp timer support 24v, so should I get a 24v transformer?

I'm pretty new to this stuff and I'm wondering how these 2 strips and the bar will handle the power if I get a 24v. For example one LED strip only needs 3 watts, if I hook it up to a 24v transformer would it burn out or does it only draw just the required 3 watts?
