And whats written on yours? Or no sticker?
Edit: 2 strips(2ft) = 50w (what you measured was AC)
1 strip = 25w = 1050/1100ma = 22.8/22.9v
And actually I wouln‘t have words to provide you a proper lesson on how you use a multimeter. But for me, youtube video worked wonders... 15min and I was already able to measure everything. But to be honest, I started with a battery, just to be sure
And I got a question myself, using one HLG-60H-24A now on 14 strips in parallel. If I want to double the power, can I take another HLG-60H-24A and put it in parallel on the other end? I read about it, but I am not sure, if I got it correctly (was it parallel, or series?). They used two driver from both ends, to power a very long strip, so they didn‘t had a power drop at one end. If that is workng, it is also working with a diffrent driver, e.g. HLG-120H-24A?
