It Should make you Wonder

It really should make you wonder when you have a LED Sales rep / Lighting Engineer talking to you over the phone trying to sell you their LED's who are a Sign Company NOW also branching out to sell their LED's which I think everyone has seen in all the sign magazines now where they ship you off their little "light box". I'm sure you know who I'm talking about.

I asked him where their LED's are being made, "China...they're the brightest....with very little light decay and will last 11 years" he replied.

"I see........Uhh..who is the diode manufacturer?" I replied

"I Can't tell you" he said.

"You don't know?" I followed up with.

"No, I know....I just can't release" he said.

"Why is that?" I asked.

"It's proprietary information...it's our secret sauce formula you know?"

"It's a secret?....that makes me cautious actually. As you know there are a lot bad diode manufacturer's and grades of each Diode......that doesn't make me confident in not knowing who you are using" I ended our conversation with.

For a LED product manufacturer not to tell you who they are using is NOT good, it also should tell you their not that confident either. It means you will be retrofitting your customers signs out shortly after!

I'm VERY confident and PROUD to tell you what diodes we have in our products, Samsung and Nichia!

Finally we can also proudly say that these products are NOT made in CHINA!!!!

I'm starting to see a lot of LED sellers claim their products are "LM79 and LM80 certified" - yet there is no mention of what these tests actually revealed. My understanding is that LM79 measures total luminous flux, luminous efficacy, light distribution, and a few others. It's not a pass-fail type of test, it's a report that can be used to evaluate a product.

Modules, etc. from everyone seem to be getting better, but it's definitely still buyer-beware.

These tests are also used to project life of a product. I'm not sure how they take a few thousands hours and say that said product will last 30k/50k without failure or very little light loss, but they do. Neon and fluorescent easy to project as it;'s just gradual but LED's, graph it and it's all over the chart, lol.

I still haven't seen a whole lot dependability on bright products for the sign industry. The Sloans and GE's play it safe on under powering theirs and charging a whole lot for it, playing it safe is equaling out to light output compared to conventional light sources. I still see a ton of failure's all around town even with new signs, and signs hitting that 20k mark. Lot's of re-retrofitting going on and lot's of people entering the game thinking they can just bring in overseas not knowing the makeup, and as you said it is "buyer-beware"

      I get emails from the mag and they have started to put early issues into an archive with the Cincinnatti public library.   it's facinating to look at the old copies, especially the ads for the various products.   EG sign lights with a hooded reflector don't seem to have changed much in design since the 1920's.    I've put a link to the archive below.  i hope they keep doing this because i'd love to see issues from the 1960's/70's when i first started helping my Dad.   https://digital.cincinnatilibrary.org/digital/collection/p16998coll17/search/searchterm/Collection of SmartWork Media/field/source/mode/exact/conn/and/order/datea/ad/asc

      Why it's best to use RED LEDs behind Red Faces

      By Rocco · Posted

      A long time ago I did a comparison between the different colors of neon with my eldest daughter.  It was for a science fair project.   We took 7-8 different neon samples (i had a ton at the time) and put a light meter on the various colors.   Clear red put out the most light by a good margin.   i don't have the info anymore because that was about 30 years ago but it does make sense to put red LED's behind red plex.    And we used to put red neon behind red faces - way back when - so red modules behind red faces is logical.

      Why it's best to use RED LEDs behind Red Faces

      By Salsa Signman · Posted

      We had a long time Mexican Restaurant customer switch out his clear red 15 mm neon for LEDs.  He thought our price was too high for LEDs so he used an unexperienced sign company and they installed cheap white Chinese LEDs behind his old faces. His faces went from red to pink (rosa) at night. Needless to say he wasn’t happy with pink faces… He pointed this out to the other Sign company, but they would not fix it. Plus, they had no clue what they were doing with the parking lot lighting as they tried replacing 400 W metal halide lamps with LEDs. He immediately called us to fix his parking lot lights because he was losing business because his parking lot was dark. He lived with the pink letters at night for a while and just recently hired us to install red LEDs and remove the white ones. He’s happy now with red faces again at night.

      This is a great comparison to show why it's always best to use Red LEDs behind Red Faces, and not use White for everything.     On the left is the one of the brightest white LEDs on the market...The .8watt BrightON II LED Module, on the right the BrightON Ruby Red…also .8 watts per module and probably thee brightest Red LED module on the Market.          When we put a 7328 White acrylic sign face over the white we get a luminance of 240 Foot Candles of Light right on the sign surface .  Now we’ll switch the White acrylic with another 7328 White Acrylic with 3M Red 3630-30 Applied Translucent vinyl and see the results.         Red is very hard to capture using an iPhone, but believe me…..in person the contrast between the channels that has the White LEDS vs the Red LEDs is large.  The Red is overwhelmingly brighter than the White with a luminance on the sign face with 47 Foot Candles….and the White LEDs with a luminance of ONLY 18 Foot Candles.         When using White LEDs behind a Red face you will lose 50% of the luminance on the sign face based on how the lens filters the wavelengths.  This is why it’s best to use Colors behind Colors….Most of the time!
