Yeah I think I'm just going to use height instead of a dimmer. I have lights I can use for seedling's.

HO T5’s? Can’t beat ‘em…
Will do. I have a room that I'm turning into a big pantry and part of that will be made into a grow room. Gonna be awhile. Work has me busy right now. My Oklahoma projects are keeping me busy. And I have some in Arkansas.
Yep and I have some HOT5s.
LEDs without a dimmer are usually incompatible with dimming via pots or regulators. It's not the LEDs themselves usually, but the circuit board that powers them. Lower the voltage to the circuit board and you will likely get flickering lights or no lights at all.
Yeah I'm just going to watch my distance to canopy. I need to find what the best distance is. I've read you can do 12" but trial an error will tell me.
The video I posted shows the Pot being attached at the driver
Those drivers were made to be dimmable and have inputs specifically for using a pot as a dimmer. It will depend on what comes with the SF 4000.
No Really LOL
Just kidding I have an Electronics background from many moons ago
Things do change, But I have done it with Meanwells

Not saying it's impossible, but the drivers/supplies can make things difficult or easy depending on how they are configured. The ones in the video you posted are made to have dimmers.
The SF 4000 without the dimmer switch can be dimmed by removing the box from the light,,turning it over and using a screwdriver on the back. There are two places. The one on the right is the one you use.

Thats the one Yes I have read that nice find
It will lower your voltage as well as raise it slightly in each direction
Yep. Turn to the right and voltage goes up,,to the left dimms it.

Fking Stoner 
By the way,,what was we talking about.

I have the SF 4000 and have disconnected two wire on top to dim the light down. Thank you Hopper for the information. I'll use it.
No problem Ness. Had to do some research but it wasn't to hard to find.
