EXIT Sign LED Retrofit Lamp, retail $Unknown

This is an LED retrofit lamp for the incandescent lamp used in many of those "EXIT" signs.

It uses 20 semi-diffused red LEDs, and is not only made to last a lot longer than incandescent bulbs, but consumes a lot less power than incandescents as well.

This means that an EXIT sign with a battery backup will operate for a significantly greater period of time during a mains power failure than it would with an incandescent.

To use this lamp, remove the side panel(s) of the EXIT sign you're installing this into as though you were relamping it with a normal bulb.

Unscrew the old bulb, gently place it on the floor, and {spoken like Butt-Head when he finds an overhead projector in the school parking lot} SSSTHHHHOMP ON IT!!! YEAH BREAK IT BREAK IT BREAK IT!!!. Or just throw it into the waste bin (wastepaperbasket) if you're averse to breaking things.

Screw this lamp into the female candelabra screw receptacle occupied by the old lamp, replace the side panels, and be done with it.

This product is intended to be operated from mains power, not batteries, so I do not have to tell you which part to remove, huck down the basement stairs into the room crawling with thousands of hungry piss ants, and then rather emphatically tell you not to.

The only warnings I have regarding its use are that it must ***NOT*** be used in a sign controlled by a photoelectric ("day/night") sensor or one that uses a battery backup system AND if the old lamps were incandescent. This bulb will rapidly (and possibly quite spectacularly) fail if this is done...you don't want baby tarantulas or mourningcloak butterfly caterpillars (larvae)...I mean an UNWANTED FIRE!!!

To be a bit more technical here, this lamp would be a lot happier if it is fed 110 to 130 volts AC 60Hz AND that AC power has a sinusoidial waveform aka. a "sine wave". EXIT signs using a battery backup and incandescent light bulbs typically use a DC to DC or DC to AC inverter, and those inverters frequently output a square wave or a sawtooth waveform, not a sine wave. And this lamp would not like that at all -- it would very likely soon fail, and possibly with fire involved.

Actually, if I remember correctly, this bulb *DID* perform well on a dimmer-controlled circuit, but since I do not have access to such a circuit now, I am not equipped to test this.

This is a retrofit lamp designed to be used in EXIT signs, not a flashlight meant to be bashed, thrashed, trashed, and abused; I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of a porch, use a medium claw hammer in order to smash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island {In the episode "Les Saves the Day...Again", Paulie Preztail says "Hey, ever wonder why this park's called 'Mount Erupto' anyway?", then Franklin Fizzlybear says "I think its an old native term. Means 'very safe.'"}), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights may have inflicted upon them.

In fact, those photographs, plus the spectrographic and beam cross-sectional analyses located directly below may be pretty much "it".
