It’s efficiency is not as good as QB ~1.2 (650) vs ~2.5 (QB)

I can pick it up for 400, with a ph meter with it

@Bobbydigital @WickedAle

I have a qb 260

Sounds like a good deal, but it’s a burple at what looks like 1/2 the efficiency so is it better that a $400 equivalent setup with 3000K Samsung LEDs? @dbrn32 probably should weigh in.

What i am hoping to find out is.

Is this light worth 400 used. If so, what would be the closest equivalent of a HLG qb board.

They are older leds pre-2015 and a lot of blue with less red.
I got my made in 2015 light’s cheap ($100) and run a 2x288 QB in there with them and it kills it
$400 a lot of money, sorry I cant help more

I trust HLG, not sure I trust all the brand’s I see out there. And when someone attached a 1600 price tag on a light. Well is this just a second grade light or does it preform?

If thought was worth a crap, it might make the PH meter that comes with it look better to me.

You do hydro, we welcoming you into the fold? When you said meter was just hoping it was maybe a bluelab pen but damn. that even used is $200. Your dealing with a plant that can make $2000+ of bud you would never even see selling. WTF buy it :clown_face:

Lol, yeah I didn’t want to drop the bomb on the meter until i found out if the light was worth a crap. Didn’t want the meter to weigh in on the decission.

It’s pretty much typical blurple performance, but it is a high powered fixture. I’m not really aware of anything that’s equivalent, it’s a little higher flux than a hlg-300.

Is it’s performance worth 400 for a used light?

Seems kinda high for a burple

Not in my opinion. Maybe if it came with a $250 ph meter.

Don’t sound so good to me then, the light to me is worth about 100 bucks. The meter, 250?

He needs to come down on the price

The whole reason I nibbled on the blurple.
Was the Blulab Guardian Monitor System.

It’s like selling a fresh feed, with a new car.
