Ok so I have a 32 x 32 x 63 tent growing msnl bluetooth fem auto in streach they shot up quick and tall getting light burn I'm up as far as I can go have it zip tied to the top bar there in flower did some bending and snapping to try and help them not get light burn . So my thought is to put window tint on the light to chill it out a little any thoughts

How much does the 200w draw from the wall? 75-100w? You'll probably need 1 more or something to suppliment it to get around 180-200watts. A good number to shoot for is 30-35w sq/ft and adjust accordingly, since you really have no idea of the quality of light produced by your leds it's hard to get an exact number. 30-35w is a good ballpark.

*edit*

Looking on Amazon that 600w draws 269w. That's like 43w a sq/ft. Also the reflectors on that probably burned your plants because it focuses the light at more of a beam.

Do you have any info on the 200w ufo?

2) LED Power : 200W
3) Working Voltage: 85v - 265v
4) Lumens: 6000-7000lm
5) Product Weight:1.2KG
6) Operating Temperature: 90°F -110°F (32.2°C - 43.3°C)
7) 12bands Spectrum: 430nm 450nm 460nm 630nm 640nm 660nm, 3500K, UV,IR,Yellow,Orange.
8) Product Dimension(Diameter*Height): 175x60mm (6.89x2.37inches ).
9) Coverage Area about 6 x 6 Square Feet ( The lighting area and the height are changeable according to different plants and environments )

Yeah, that won't be enough to flower a 2.5×2.5 area. That 6×6 claim is total bs. Maybe a 1x2 area.

Do you have a multimeter? Or kw meter?

No I do not have a multi meter or a kw meter.
First grow learning as I go. I have grown with t5 years ago 18+ yrs figured I would try leds and see how it would go

Most of those cheap Chinese "full spectrum" leds are really inefficient. Pretty close to hps. They do grow some good weed. I bought a 150w ufo off ebay just like you, and it only draws like 56w. So 1/3 of the advertised wattage. Some of the more expensive ones get about 50-60% draw.

You could supplement that light with Screw in cfl or leds for now to finish the grow.

Are you very good at diy? Can you build things and have the ability to do minimal wiring?

Yes I can do carpentry ( spelling sucks tho)
Agree with the Chinese junk I was in a pinch.
Appreciate the help oh happy father's day if you're a father

Because of the reflectors I would hang the Jhotec full spectrum at least 24" above the canopy. It has also a bit to much blue for my taste which also can cause burnings(blue photons carry twice as much enegy like a red photons).
I assuming it's too late to send it back, right?
So then I would try to remove/deactivate ⅔ of the blue and coolwhite diodes. Because of the veg and bloom switch there are probably 3 or 4 seperate drivers inside this light. Probably two for the blue/white/red veg switch and two for warm white,/red,/deep and far-red bloom switch.
Disconnecting one of the veg drivers is maybe not a baddest idea.
Mars, Viparspetra and literally all the other shitty blurples out there always use too much blue. So you still get problems with bleaching despite relatively low radiometric intensity and the lense-reflector combi makes it just more worse.
But with one driver less you will loose probably 50-60w at the wall.

Thanks bud, same to you!

What country are you in? I might be able to work up a nice strip light build for a 2x2 for around $100-150 that would work great in a 2x2 space.

Then you can also aluminum.
You need a 2' x 2' frame made up of aluminum L-channels and a handful of Bridgelux EBgen2 or Samsung F-Series gen3 strips and for a 32x 32" area a Meanwell HLG-240H-20A or 24A (20A for Bridgelux, 24A for Samsung)
The stripes will be simply glued on aluminum c-channels(with doublesided thermal tape) and are connected in parallel circuit to the driver.
A 250w light could be done for around 200$(not bad). With a DIY strip light your effiency boosts from 1,3-1,5μMol/j currently to 2,3-2,5μMol/j when the new light is finished.
If you read anywhere from 1.5-1.8g/w with LED, probably strips like these or white COB's were involved.

Just got a buckeyes hat for father's day!

Ok here is a build using the eb gen 2 3500k strips. We'll shoot for 200w, about 35w sq/ft.

10 eb series gen 2 2' strips 3500k
https://www.digikey.com/product-detail/en/bridgelux/BXEB-L0560Z-35E2000-C-B3/976-1734-ND/7907663
$65.50

Hlg-240h-c1050b the B is for dimming purposes.

10 1" aluminum heatsink from heatsinkusa.com 2' long
https://www.heatsinkusa.com/1-000-wide-extruded-aluminum-heatsink/
Approx $45 shipping

1 4ft 1.25" punched angle
https://m.lowes.com/pd/Steelworks-4-ft-x-1-25-in-Plated-Steel-Perforated-Angle/3053587
$10

100k ohm linear taper potentiometer to dim
$1-5 on ebay

3 barrel wagos
$1-3 on eBay

For the Samsung strips

6 3500k f series
https://www.digikey.com/product-detail/en/samsung-semiconductor-inc/SI-B8U261560WW/1510-2218-ND/6624002
$95.10

Hlg-185h-24a (internal dimmer pots)
$51.32

The rest is the same. Except no external potentiometer is needed.

You could also use an hlg-185h-20a on the bridgelux eb gen 2 build to save $10-15, and have internal dimming. Being able to set a constant voltage helps protect from thermal runaway.

Go to ledgardner.com and check out the blogs and forums for info on driver and builds.

Awesome thank you
Strange thing is I think the window tint is actually helping you can see the bottom leaves are little burnt on the right side I left side look good
I purchased some smart pots for next grow there much lower than 5 gallon buckets no nuts organic grow spring water so it's not nutrient burn.
Thanks again for the diy tip on the lights I will start gathering things for the next one.

I don't see any light burn in that pic. Light burn is going to hit the leaves closest to the light, not the leaves down low.
