RE: Color Kinetics - Bigger PSU?

["Rob Mouser" <rmouser@xxxxxxx>]

Thanks Tony

Can I ask a dumb question? Oh good!
If I get some of these PSU's would I do the units any harm by not having all ten switched on or do they just draw as much as they need? Just
thinking about a gradual install scenario.

Many thanks
