The Mythbusters tested it 20 years ago or so.
Their deathmetal tent worked best but I believe they concluded in general the more noise the better.

Yea, I’m not going to believe anything on TV.

Good thing I have a way to test it myself!

But I won’t, I listen to metal/classical/beach music already.

The Mythbusters show was pretty good about testing such ideas objectively. I didn't imagine their record is 100% but I think they got it right the vast majority of the time.

Yea, it is just the TV thing.

I haven’t owned one in decades for good reason.

I do not need to channel daily programming, my mind is perfect the way it is.

Testing!

It is going to be good to see how far I can push these EB3 Slims on 1/16” aluminium angle before moving forward. I know the next array will handle 200W on the backing, nominal current, but pushing up to 240W is concerning.

The smaller strips are doing fine with a +64mA over-drive. It is time to see what +150mA will achieve!

Cheers!

I bet you cannot tell which one is 100W, 150W or 200W.

18” height:

500’s ppfd @ 100W
700’s ppfd @ 150W
900’s ppfd @ 200W

I’m getting a better diffuser to see how accurate these measurements are. I was right to estimate 150W being the best for a veg lamp. Using this higher than 150W is just stupid. It can be done, but it would be stupid.

I’m going to hook up the 240W now.

Should be 20W per strip.

Should be more than 1,000 ppfd.

Yes but will it play reggae for your plants to help them grow?

Yes, I actually once saw a study that purported to prove that playing music for your plants encourages growth and reggae worked best.

Oh, you know it man! What kind of screw-in (around) household LED bulb fixture would be complete without 2 bluetooth music\ RGB light show bulbs, for full 2 channel stereo operation?

I'll also have an array of over 2000 40k & 25khz 16mm ultrasonic transducers built in, to create an impenetrable gnat proof force field bubble under the lights.

And a "photonic fence" with AI bug tracking laser beam guns all the way around the perimeter.. Incase one gets passed my HEPA filtration systems.

These lenses make me ask questions; they're clearly designed to manage the light that's leaving the diodes in the plane perpendicular to the strip but what about all the rest? The light spilling from the ends is significant and I'm not interested in lighting walls and floors...

I would probably just cap the ends off, or add mini reflectors at the ends of each strip.
Also, they are pretty flexible from what I've heard, the EBs anyway... You could add the long custom linear lenses, and bend the whole lensed off strip into a slightly curved parabolic shape, to help focus them even more from the other directions.

EB’s would make a perfect panel. No heatsinks are required, open-air @ 20W is achievable with plenty of circulation.

I bet we could hang these like a curtain.

Yeah, I thought of using led strips that are retractable like window or sliding glass door blinds (with the slats spread further apart though) for vertical growing applications over a decade ago.. Now the strips are way more light, slim and powerful, and definitely could be a reality in that kind of config. Imagine having scrogs or vertical racks packed tightly together, with retractable lights in the middle that can move in or up and out of the way, so you can get in and work in the same space that fixed lights would normally take up?

You could add strip "blinds" to the door opening area of your grow tents, where people normally never get to add side lighting from because it would be in the way.

Zip open the tent, then pull the draw string and all the light strips move up towards the ceiling and allow access.

Have full 360 side lighting all the way around when the tent opening is closed up.

Barn doors in both directions. Off-set track, off-set trellis. Just slide the door, do your work, slide the door back. The doors could also be on a track to move to and fro.

I’m going to do the opposite. 960W in the center, probably more now that I know what the EB3’s can do as well as I found access to 240V!

Think of the sun, inside of a 4x4.
