MOQ = Minimum Order Quantity Hence MOQ = 60 @ 1.71 = 102 Plus Shipping. For Those Of Us Using Reflectors And Replacing Every Panel With Cob Bars I'm Going To Need 48 Reflector's and I Think Mouser Price Is 9.70 So 9.70 x 48 = 465.60 . So By Ordering Every Reflector I Need Plus Some Spares At A Saving of 362.50 Siskel And Ebert Would Give This 4 Thumbs Up

I could see me buy 60 , like Dawg I like spares & that price you'd experiment on a few as well

I have seen this reflector but it came with a crappy burple cob with square LES.
What cob is in that panel ?
Looks like a Round LES

Here is a pretty good read
The beam angle of a light seldom makes headlines. You often have to delve deep into the technical specs to this figure (if it’s even listed at all). That’s too bad because beam angle tells the story as to what kind of light you have. Some lights are purposefully designed to be wide angle while some lights are intentionally made to be narrow and focused.
Beam angle can make all the difference in what you’ll actually see. For example, let’s imagine you are standing at the tee box on a dark golf course at night and are holding a 200 lumen light. If your light had an 8 degree beam, you’d probably be able to see the flag for that hole. If your light had a 45 degree beam, you wouldn’t see the flag but you’d be able to tell if there were any trees, coyotes or hazards in the periphery. In other words, you’ll see completely different things even though the light output is identical.
Beam angles are as important a factor to consider when buying a light as width options are for shoe purchases. It’s possible that 80% of people don’t care much either way (about shoe widths or beam angles) but it matters a great deal to 20% of you. A person with a wide foot will be miserable and get blisters in narrow width shoes...especially if they ran a 5k or marathon in them.
Not all shoe manufacturers offer shoe width options (narrow, standard, wide) but those that do make sure it’s easy for all to see. Similarly, not every light manufacturer offers a wide array of light beam but here are the main three beam categories:
Failure to consider beam angle (or the light type you need) may lead you to selecting the wrong light for your needs. If you’re looking to avoid tunnel vision, then don’t buy a spotlight. If you’re for a focused flashlight that throws far, then steer clear of wide beam lights. The wrong light beam (like the wrong shoe width) can lead to a great deal of frustration.
THE TAKE-HOME LESSON:
Lighting companies are generally consistent with how beam angles are reported. Find out the beam angle of the lights before you buy and make sure it’s in line with the type of lighting you’re looking for. Make sure it fits your needs.
DO NOT just buy a light and hope for the best as you might regret it later.

- Focused / Spot lights: spotlights generally have focused beams of 20 degrees or less. These lights enable tunnel vision and are great if you’re primarily looking to see far ahead.
- Combination: these lights offer a combination of focused and flood lighting. These lights have a beam angle in the range of 20 to 45 degrees and are designed for general use.
- Flood lights / area lights / wide angle lights: these lights have a beam angle of 45 degrees or greater and illuminate a wide area so that you can see the big picture (a la a camera wide angle lens)

After reading about LEDs on this forum for a bit I've learned a lot. Reflectors are nothing but yagi antennas. Redirect and form rf if you will. All measurements on a dipole are referenced to an isotropic source. Sphere for LEDs. I use no reflectors or lenses. I run at 100w a cob though and get a good bud size 2 ft plus down. But I grow in a very small walled area with mylar. The lenses I tried were too tight of a beam for me. It was the widest at the time I could find on fleabay. Ymmv

So there is clearly two different sound I can hear....
Yes reflector are the thing to do/add
No you don't need some...
Same for lens...
I guess I will just try the cheap one from kb...2.50$ I guess with adapter for 90º reflector and see what happens...and if I don't like I remove it!
And if I look into my memory I remenber my first reflector for hps...it was a piece of aluminum...then the adjust-a-wing (much better)...and now the magnum and OG black...I mean when a big company will design horticultural reflectors for cob with a mylar coating or with whatever works best for us we will almost all use some!
