Sweet! Thanks 
I couldn’t remember but know it’s more than 150w for sure.

Yeah, ViparSpectra gave me that 200w one to test and then gave me 2 x 150 watt lights to replace it. Worked out good for both of us

I have 4 of these in my 4x8. I really dig the lights. Definitely get the job done and some. I haven’t been able to run them past 70%. I’m thinking of just running 3. I’ve been pretty impressed with Viparspectra.

I love my viparspectra xs1500 hands down. Might even like better than a bigger light from different brand but that’s because I haven’t had chance to push bigger light. I think you’ll be very happy with your results.

I have 2 xs2000s that I ran and really liked. I actually have and xs1500 and an xs2500 sitting new in boxes I haven’t broken out yet but judging by how the xs2000s did I’m confident they’ll be great. @JohnnyPotseed and a few others were quick to vouch for Viparspectra when I was trying to decide what to buy so that was all I needed to hear. They were right.

Sorry I missed the pro part I just have the xs1500. My bad. Still love the light though.

Update: my pals double grape auto is doing well for his first time growing anything. Under 1 xs1500 pro in a 2x4. BUT he’s getting pretty significant leaf curl that looks like light stress to me. Serrated part of the leaf edge folding inward…he has yet to put the light above 50% and is doubling the specified hang height.
Plant is 16-18" tall and throwing pistils.
Probably mentioned above but I missed it. My one complaint about the xs150 pro is the stepped dimmer knob. I like to be able to adjust the dimmer to any intensity I need. Other then that they’re a quality light.

Have you ever had light stress issues with it at recommended hang distance? I was surprised to read that they specify 11" at all power levels.

I hang mine at 18 inches
11 seems to make them sad

that par map is pretty stellar. i also like that its almost 40 inches across. wall to wall. did you switch from quantum boards before the ks5000? if so have you noticed improved development(larger denser nugs) around the outside edges of the tent?

The KS5000 is the first LED I’ve used and is still first grow w it. It definitely seems to do the job.

So you can move the transformer to the outside?

It sure looks like you can! Basically its 2 xs1500s with a spacer for a 2x4 area. But they made the driver remote. Nice looking light

I have not tried the new model but they did send me 2 of the XS1500 pros. They don’t have the added UV nor the rod that holds them together as one light but still, they do a great job in my 2x4 tent. A great value product IMO.

Yep, has a cable long enough so the driver can be kept outside the grow tent 
I have the 2023 equivalent of the model you linked and I keep the driver outside my tent
