LED ''SIGNS'' Sign, retail $121.50 (www.gershelbros.com...)
Manufactured by (Unknown)
Last updated 06-21-12

This is an LED "SIGNS" sign, designed to be hung or mounted in a retail store to indicate to your shoppers the presence of a "Signs" section in your store - that is, a specific location inside where they can find signs and/or materials for making signs.

It has 133 LEDs (28 red, 12 yellow, 30 green, 35 blue, and 28 purple).

SIZE

Plug the cord from the AC adapter into the female receptacle for it on the upper surface of the sign, and plug the large end into any standard (in the United States & Canada anyway) 110 to 130 volts AC 60Hz power receptacle.

On the lower portion of the sign, there is a short pull chain "on/off" switch. Pull down on this chain until it clicks and then let it back up to turn the sign on.
Do the very same thing again to turn the sign off.

Hang (with the included chain) or mount the sign so it will be readily visible to customers in your store looking for signage materials.

This product is not battery-powered; so I do not need to tell you which part to remove, throw in the wastepaperbasket or flush away, and then tell you not to.

This is an electric "SIGNS" sign, not a flashlight meant to be carried around, thrashed, trashed, and abused. So I won't throw it against the wall, stomp on it, try to drown it in the {vulgar term for feces}bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannoñata (I guess I've been watching the TV program "Viva Piñata" too much again

- candiosity is usually checked with a laser-type device on a platform with a large readout or with a handheld wand used by Langston Lickatoad), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights may have inflicted upon them.
So this section of its web page will be rather bare, when compared to this section of the web page on a page about a flashlight.

I believe this sign is intended for indoor installation only; it does not appear to be very weather-resistant, and it's level of water-resistance is rather minimal.

The purple LEDs aren't true violet; they're a phosphor purple who's light consists of a ~455nm blue native LED band and a ~640nm red phosphor band. These two wavelengths mix to create a purple color.

TEST NOTES:
Product was purchased on the Gershel Bros. website (from their 2007-2008 paper catalogue) on 09-30-07, and was received on the afternoon of 10-16-07.

The AC adapter is rated to output 12 volts DC at 1,000mA (1.0 amp).

UPDATE: 04-26-09
While performing spectroscopy of its LEDs with a different spectrometer, I took note that this product had not been rated. This situation has now been rectified ("corrected" - *NOT* converted from AC to DC

).
It earned a full five stars on this website!!!

Here's the sign in its current installation:

That clock on the left that looks like a gigantic wristwatch is my Infinity Optics Clock, hanging to its left is my Patrick Star plush, and that large digital clock to the lower right of center is my GForce Power LED Calendar Clock. The rest of the framed & unframed articles visible here are some dead insects (butterflies, moths, and dragonflies), a small framed drawing that my sister gave to me approximately two years ago, a larger framed "photo montage" of my immediate family and of Mt. Juneau in my old hometown of Juneau AK. USA, a photograph of the Star Trek: Voyager crew on the bridge of the starship U.S.S. Voyager, and an Alaskan woodcutting that I made and painted in 1975.

UPDATE: 05-11-09
I noticed that one of the purple LEDs (in the last "S") had become pushed inward; however, this was an extremely easy fix requiring nothing more than a screwdriver (to remove the rear panel) and a few minutes of my time. Removing this panel, pushing the offending LED back out, and reattaching the panel was all it took.
Because this was such a darn diddly-arn easy repair, no stars will be deducted from its rating.

UPDATE: 11-21-09
Maybe I'm just seeing things, but the purple LEDs in the last "S" appear to have a lower intensity than they did before. This intensity decrease is noticeable, but not astronomically huge.

UPDATE: 10-05-11
Three of the LEDs in the green "G" have inexplicably failed following an intracity move I recently made.

To wit:

I took the back off and checked for a discontinuity, and found none. So one of the LEDs has failed "open" -- thus causing the other two in that string to also go dark.

UPDATE: 11-07-11
The Power switch has inexplicably failed; this is a mechanical issue with the switch itself. I jumpered the two switch leads and restored operation that way -- though I have to physically unplug the PSU any time I need it off.
Therefore, that somewhat dreadful "

" icon has been appended to its listings on this website, denoting the fact that one or more parts have become busted but the product's functionality itself remains intact.

UPDATE: 06-21-12
I have effected temporary repairs which allow for two of the three "dark" LEDs to become illuminated again.
To wit:

See how just a single LED is out now?
That's the one that failed "open"; I bridged it with an LED of similar operating chemistry (InGaN) so that the other two in the series would not be brighter or dimmer than the others.
If I can find another T1¾ (5mm) round green LED in a diffused body (and of the same or extremely similar operating chemistry), I can make this repair permanent.

PROS:
Smart looking black background
Very nice "rainbow" selection of LEDs
Extremely colorful and gay*
Visible from quite a distance away and through a wide viewing angle as well
Because it uses LEDs, power consumption is rather minimal

CONS:
Not very water-resistant - but I do not believe it was ever intended to be.
This will ***NOT*** affect rating!!!
