Anyone use one of these LED dimmers?

Just my two cents here...if you want to be able to dim your LED's the most effecient easiest way is to start off with a dimmable constant current driver. I am an electrical engineer (mostly control systems) and after doing tons of research I used the dimmable constant current drivers from Thomas research products.


And to confirm what others have said, there is no way you can use a voltage regulator to dim LED's being driven off of a constant current driver.

Ill throw my vote in with this one. I am not an electrical engineer but I have done enough electrical and electronic courses to know this is the way to go.

The TR drivers are a little more money, but theres a reason for that, they aren't susceptible to inrush current like the Maxwell's are, there dimmers are built in with a few different options, and the sizes you can get them in let you use only two drivers (even for large arrays)

Thanks for the replies fellas. I've done a small LED build for my freshwater nano using dimmable meanwell drivers and was just wondering if there was a cheaper alternative than going with the dimmable version of constant current drivers. I'll check out the Thomas Research drivers as my next project will be using quite a few more LEDs than the previous one and I'd need quite a few meanwells to get the job done.
