Quick notes…
When trying to use a mix of different strips in the same fixture, be sure to check voltages and max current ratings.
You can use strips of different voltages in series, but not in parallel. Just be sure the total voltage of the strips in series match up to the voltage range of the driver.
The current rating is just the opposite - strips wired in series should all have the same (or close) max current, but strips in parallel can have different current ratings as long as the voltages match.
Meanwell drivers are at max efficiency when running at full power, so dont worry about running them at or even above max rating. They can easily be pushed 10% or more past the max as long as you have good air flow around them. Id recommend you keep the driver outside the tent in a place with good air flow even when running below max…
Oh - dont cheap out and under size the wire you use that runs from the driver to the fixture. The longer the run, the larger the wire needed. Also, if you use connectors anywhere, make sure they are rated for more than the max current you expect to see.
