Optic Lighting Vero COBs updated

Does someone know where this 'x3' lenses can be found?

Just go to alibaba or ebay and search for cob lens..

They are categorized by size in millimeters, not sure how big the optic one is...probably one of the bigger ones. I don't think x3 means much, not sure how they came up with that. You could just measure the cobs LES, phosphor surface, and get one a bit bigger.

@SupraSPL -How evenly is the light distributed under the lens vs a naked emitter?

There is no way to magnify photons. Only gather them into a tighter beam. So 3x is just what they call it. Ledil makes a 78* lens. And there are a bunch on Ali or other general sites like Pos said. The generic ones seem to cover more than just the cobs, so they aren't neccesaiy cob model specific.

I like the design alot its so simple Supra is it loud? My apolo/gn have alot of screws also its very noisey sounds like its going to lift off.

Good news, Optic is glad to hear the positive temp droop results and offered us a discount code, 10% off Vero lamps plus free shipping, code is SUPRASPL Very cool of them and for full disclosure they offered to let me keep the test lamp, but wisely did not mention that until after the testing.

Light distribution pattern at 12", covers a 2'X1' space at this distance.


That is 53.5W/ft², probably too close. I will check it at 18" and 24".

lol no rocket launch here, runs softly. I tried to think of something to compare it to, the air coming out of my heater vent is louder.

LOL I knew it ! You run a side business!

(lmao, true or not, )

If anyone can put up a link for some good lenses

That's a hard code to remember

Honestly, Optic did what I cannot do, produce a great performing prefab style COB lamp. My niche is sourcing parts, consultation and "built to order" custom lamps, but I do have a "day job" to attend to. I hope Optic makes a heap of money because they are the first to pull this off. But there is no doubt that other prefab COB lamps are coming, optic struck first, putting pressure on the other great lamp makers to step up their game. Capitalism working and it benefits us growers.

I guess what I meant was, what is the relative intensity in the center vs at the perimeter? I don't have a lux meter to test the effects of a lens.

How long do you think it will be before we see the first COB based weapon of mass destruction?

Cover the moon in cobs, and lenses and mirrors to aim the white light.

Or use it to wake up people's plants at night. Now the moon is bright enough.

O gotcha, while I am at it I will check the boost of the lens. Because the COBs are so high powered (53W), the distance to canopy will be large enough that the lenses make a HUGE difference.

From a distance of 16" from COB to test surface, with lenses, the lamp is lighting approx 30" wide X 18" tall or 3.75 ft² that is 28.5W/ft².

Without lenses:
center 19000 lux
north 6" from 17200 lux
west 6" from center 17000 lux
west 12" from center 12500 lux
west 15" from center 10000 lux
sw 12" from center 12000 lux


With lenses:
center 53500 lux (+281%)
north 6" from 36500 lux (+212%)
west 6" from center 33500 lux (+197%)
west 12" from center 21000 lux (+168%)
west 15" from center 10200 lux (+2%)
sw 12" from center 20000 lux (+166%)


I tried to get the camera to show the difference. In the second pic, the lens is removed from the COB on the right. The true color temps do not come across in the photo. The color temp of the bare COB is much cooler than the side with the lens. Almost like the lens converts the 4000K to a 3200-3500K.

Do you think either of these are similar to the lenses they are offering?

They're both the same (the latter one has a mounting bracket) and if they hadn't changed them since v1, they're also used in that lamp (w/o reflector).
Funny how they claim 98 & 99% transmittance.

It would be nice if anyone finds a good lens for the 3070 series to put up a link. I have found a lot but not sure which one would work best. Any ideas? I'm sure a lot of us would appreciate it.

The lens above are not designed for Vero29 so I suppose you could use them on CXA3070 as well.

It is too small for CXA 3070( ABOVE LENS) with cob holder, the holder it says is 50mm.

I gambled and pulled the trigger on some lenses, $37 for 8 delivered. I've thrown more away when I couldn't
afford too. See what happens http://www.lck-led.com/degree-67mm-convex-lens-edges-opitc-100w-p-765.html?cPath=157

I'm curious about these big #s you are getting with the lenses. I'm wondering if one thing that is not being taken into account is the directionality of the lenses. Meaning the vast majority of the light is being transmitted in a vertical direction. Without the lens there is much more side lighting. I'm just not sure that the lux reading you are measuring in a horizontal plane accurately reflect how the plant would be able to use the light. Outside, the angle of the sun would never be 90deg so I can only imagine that plants have adapted well to this angular light(side).
The pictures don't lie though, the intensity is so much greater.
