The Huble Telescope spotted what can only be described as an alien spacecraft headed directly for us! The original photos are yet to be released to the general public, this is the artistic portrayal based on the verbal description of a key scientist whistle blower. They expect the vessel to...

Oh yea, don't forget to wear your Hendrix shirt.

I've always sped my metabolism up and then slowed it down to pass the test. Lots of protein and carbs, water and whole milk, skip breakfast the day of but have coffee then water and piss until the dark yellow goes away. Hold it until you get there and tell them you really need to pee.

Oh yes! I've been running some figures on different tent sizes and LEDs. If you have a good environment and the right lights I could see getting more than 50 g/sq ft.

There is no comparison to your fixtures and anything on Amazon. I'm actually nervous! Watching your grow day to day, the wanton abuse, constant attention to detail, troubleshooting.. ya know, the @JohnDoeTho technique.. heh I'm wondering if I'll need to drop my fixture on my plants in order...

Results can be skewed. It wouldn't be the first time.

I don't discount blurple fixtures. @JohnDoeTho

I don't have time right now to pick apart that graph. just looking at it right now the numbers don't seem to match the data sheets.

Gavita is owned by Monsanto, and it is a HID. :leaf:

It is all about studying for the test.

Don't use 25° Tc.

Your numbers don't match the sheet you posted. Don't use 25° Tc figures.

CXM22 54V 1.1 A ~7,000 lux 59.4W 117 lm/W That's comparable to any HPS.

I Googled for the data sheet and that is what I found.

I found a BD, 90 CRI @ 3500K. That should be estimating about 5,000 lux per COB? 50.4W for about 99 lm/W? These are all estimations as I'm walking down the street and I don't have a pencil and paper to calculate.

Specs? It is all about the Maths.

+1 Bridgelux Vero29C @ TastyLED.com

The CXM22 is listed as a 34V chip, @ 1280 mA for 43W. That's about 5,000 lux, ~111 lm/W. That COB is comparable to any HPS. That's at a 85° Tc. The Vero29C is listed for 69.4V @ 1710 mA for 118.7W. That's about 16,500 lux, ~155 lm/W. That's at a 85° Tc. These are what the manufacturers...

The Tasty website should have diagrams on what they suggest to use in different spaces. That fixture is actively-air-cooled which means you could drive them harder than the 45W they are capped to with the driver they come with.

The Bridgelux Vero 29 C is putting out about TWICE the light as the CXM22 at a lower amperage. I don't know about spectrums though, Google data sheets for each and you will see for yourself. :leaf:
