K3 Series2 XL600 LED Equivalent or similar

You could also swap that driver for the 320 and go that route for a few extra $

I did copy , I have to look into detail it’s going to be my first Diy light , so that list looks a lil overwhelming for me now

It’s really just a comprehensive list of everything the full hlg kit would come with for $500

The actual putting it together is a breeze!

Thank you everyone for the expert advise and taking the time to respond , now I definitely be able to get a light soon since it’s only half price

And that list it’s for the rspec xl right ? Damn I didn’t know , so I can get a even better light if I do it this way

Yes that’s correct. And if you built 3 260xl you’d be paying 300$ a unit if you go this route

320W vs 250W 320 all day long. It has a dimmer
It is not uncommon for experienced growers to run 2 x 260 rspecs in a 3x3

Damn that’s crazy how much light plants can take in , definitely gonna upgrade for the rspec 260 xl - so this is the list for what I need for that light correct ?

And as well I’m a lil confused with the price line , if I go with the diy rspec 260 xl is that 600 or 300 ?

It would include everything and you’d get a spare pcb board for same price as a single hlg 260w kit if you buy the single option at the same price.

Tho a free rspec pcb board is worth the hassle

If you do 3 it reduces cost overall 70$/ 260wkit and covers shipping from hlg

320 for shizzlee I like having ability to overpower so I know I’m not underpowered…

I run 2480 watts in 8x10 of greenspace in a 10x10 I’m running a lil over 30 watts per square foot which is rocking a space with full spec hlg lights go big or go back to the store eventually


Ok so I’m getting ready to get this for my gorila grow tent 2x4x7

Any input before I order ?

@beardless @PharmerBob @dbrn32 @BobbyDigital

Other than to say I WANT ONE! Excellent choice. A lot of people go with the 260 XL. I like the 320 XL because of the additional horses. I have a 3x3 gorilla tent and am very happy with it I hope you will be with yours.


I had to remove link, they aren’t approved vendor. I would look around online for coupon codes.
