260W QB V2 RSPEC LED KIT
Does anyone know what this light is set to?
And is there a stop on the dial or will it just continue to spin and spin.

I have a timer, nothing special. But what is the actual light brightness set to?
Bright as the Sun. These lights are so bright you need to wear sun glasses to keep your eyes protected. Its a Rspec and they don’t say. But you can take this to the bank and cash it that these lights are no joke.
Yeah I blind the shit outta myself all the time. I emailed the company maybe they can shed some light. I’ll keep posted.
Here is a small sample what the HLG lights are capable of…
Pretty small plants…nothing special. The one I am holding was around 7’6”. The other in the grow room was just a single plant that filled up 16 square feet by herself. She grew herself right out of the tent. Over 7 feet tall and over 8 feet wide.

If you have the driver with an internal pot it does have a stop on the pot. and also if you get to driver with the external dial pot it also has a stop .when you plug the light up you can dial it up and down and watch the brightness .

You should have a this rubber seal on the one corner of the Meanwell driver. You can use a small Philips screwdriver to adjust from 135 to 285 watts pulled from the wall.

Your finger is almost on top of that seal which protects the dimmer.

That is probably the start of a deficiency. And I have no clue what it would be since its not stuff that I encountrr growing.
For what it’s worth, I am running two of the 260xl’s and a 600h. None of them have the dimmer pot pictured above. My kits came with potentiometers. They stop at either end and have a detent in the middle.

@Cannacure That is a different Meanwell Driver is why you don’t have a dimmable screw.
