It wasn't until I read the last part of this article my suspicions came to surface.

It's ridiculous when you start to hear about fluorescent & neon having 2/3's of their light for a sign cabinet heading in the wrong direction, whereas LED's facing one direction have an advantage. Then, "typically" fluorescent lamp light bounces 3 to 10 times before escaping out the sign face.

Furthermore, it goes on to say LED's are better to aim light in a single direction over fluorescent & neon lamps. Yes this is true, LED's have a very narrow beam of light, but as stated Fluorescent & neon lamps have 360 degrees of light, with a crap load of reflection bouncing all over a damn can lighting up that sign face. Because of this it's rare to get hot spots as you would with LED's.

What cracks me up is the fact that this crackhead brings up their engineering figures to illustrate their point on light reflection and absorption. I'm willing to bet they never once EVER built a cabinet to test their trinket theories.

UNIFORMITY

This part is a riote too. They start to say you should place LED strips on the sides, or returns to create better uniformity. HUH??? Didn't you just say LED's are already better for direction facing up towards the sign face? So now we have to place them on the sides as well to help out uniform light??? Well....don't Fluorescent and Neon Lamps already to that? That's right 2/3's, of their light go out in useless directions, bouncing 3 to 10 times before going out. CRACKHEAD!

Then, special mirror reflectors should be built as well. HUH????

I love how at the end of the article she says "LED's are more efficent when kept cool (with no temp value), Fluorescent are kept efficient when kept warm but inefficient when below 40F". What??? No temperature value for the LED's??? Why is that? Could it be because you strictly wrote this whole article to pump your companies LED line (3M LED Flexible Light Mat). Why the picture of channel letters on the article face? Hmmmmmmm

Again, I don't think these people ever built a cabinet to test their theories. Raise your hand people. How many times have we ever made calculations of what something should be, or how something should act? But when it came to the real world, the result was different?

They even have these junk infomercial articles in Canada too? I thought it was just here in the good ol US of A.

CRACKHEAD! Maybe her last name should be "ailing"

Maybe if they wanted to make a better point, or have better cred they should have talked about narrow cabinets or panels where the LED's would be greatly beneficial. Instead, they painted this story with a broad stroke brush when it should have been a narrow stroke.

That is PERFECT example as to why this forum is so important - so many people think just because someone is PUBLISHED &/or has a PhD behind his/her name that makes person an authority. It is a good start, but not carte blanche. So many people have real world experience that counts as much if not more.

Thanks for showing you (and others) READ & stay up to date - on a side note how many of us have DOCTORS who went to medical school 20 or 30 years ago and they haven't learned anything since?!!??

I appreciate the OPEN sharing of information, and to all on the board.

Does the article specify what Dr Aeling is a doctor of ? Probably an out of work artist or music major who found a spot on 3M LED's payroll. You know Eric for every person like you that can see this as nonsensical bs there are 30 people that will buy into it.

What becomes really scary is when it's the politicians or Energy pencil pushers ERRRR, bureaucrats start believing the BS and make policy based on it. Then YOU, I, and our industry pay for the Ponzi Scheme ERRRRR, Green deal.

She holds a PHD in 3M wrap certification...everyone knows that. Get with it guys!
