RW-150 4x4 foot print-12/18/24/34" PPF

Did a little thing for my buddy DXE real quick. He had asked for foot print info on the RW-150 see if he wants to check out A51 or stick with onyx on his next purchase in the future. So compiled this together. Figured I'd post here that some might find it useful for something. Here's the message I sent him. Oh yeah and these measurements were taken using an apogee SQ-120 quantum sensor.

Alright here's the data. I only did the RW-150, and the max height I could use with the little rig I made for that space was 34". So I took measurements every 12" starting with the corners/edges so there are 5 values each directions; corner, 12" in, center, 12" in, corner. So in the pics I just took the data cells from excel, centered everything and drew lines to make the perimeter. So the blue lines are the edges, and the 4 numbers on the outside edge next to them represent feet from center. So outter blue box is the 4', then 3', etc. The intersections where the numbers lay are pretty close to exact measurement points.

All units are mV*5 for units of umol/m^2/sec, or PPF if you will.

good job

the rw's drop off more on the outer area than sgs's do hmmm...

with my limited experience in LED is that not a big drop off from center to edges regarding for example the 12".

Do you have an Onyx to test? Their's is supposed to do over 1k umole at 18" correct?

Nope Just the Xgs and Rw 150. This was only the RW 150. My buddy who does is halfway across the country. LOL

Dox that's pretty normal considering the lense I believe. Though not sure if the side drop out over height is strictly because of difference from the sgs or variation from panel to panel, way it was measured or meter used. On the corners and expanding from center I could have easily lied and angled the photodiode towards the light to inflate the readings. All were taken with the sensor level with the floor parallel to the light.

Nice, have you done the xgs?

Not yet hopefully find the time sometime soon. Fucking bullshit with work.

I feel yah, no worried, we will just be waiting impatiently

Well I have to try to do it soon regardless. It's just finding the time. I'm sure people are reading this and thinking well WTF you can post on here during the day and night. Well during the day it's usually little blips of in between time. Trust me managing a molecular department comes in waves, especially since most of mine is automated. But I have to be there and make sure the techs and everything else is good. Then the evenings are a made dash sometimes, life of a single parent. LOL But like I was saying before going on a tangent, a buddy of mine just purchased 6 XGS and wants to know the best spacing for overlap to keep a good average between lights. Because overlap is nothing what some people think if you don't have your lights in the right spot.
