The P60 Drop-In Lamp is a replacement lamp assembly for flashlights using a P60-sized lamp assembly; it is designed to be operated from a range of +3.6 volts all the way up to +12.0 volts - so it can be used in many other flashlights than an actual SureFire P60 lamp assembly would be used in.

It features a Cree XR-E Q2 LED (3 watts, I believe) positioned near the bottom of a stippled ("orange peel") reflector.

Because it is designed to be operated from such a wide voltage range, there has to be a circuit of some type hidden below the LED emitter.

The second photograph above shows the flashlight I used for this evaluation: an Ultrafire WF-502B flashlight.


SIZE



Using the P60 Drop-In Lamp will vary between flashlights, but basically, you remove the existing lamp assembly & replace it with this one, and you can then enjoy the benefits of having an LED - such as greatly increased lamp life and reduced power consumption vs. the original incandescent lamp assembly.

If the flashlight you're retrofitting using the P60-style lamp assembly has no outer spring on the lamp assembly, you may remove the outer spring from the P60 Drop-In Lamp before installing it in the flashlight.



Battery changing will differ - and sometimes quite greatly - depending on which flashlight you install the P60 Drop-In Lamp in.

The only thing you should be certain of is that the uppermost battery's nipple (+) positive terminal faces the central spring of the P60 Drop-In Lamp.

Current usage measures 670mA on my DMM's 4A scale.
This current was measured when powering the drop-in lamp in an Ultrafire WF-502B flashlight with two CR123A primary (disposable) lithium cells - this type of cell is often found being used in cameras and high-powered flashlights.




Photograph looking down the "business-end" of this lamp assembly.

This is a retrofit drop-in lamp assembly designed for use inside a flashlight, not a stand-alone flashlight designed to be thrashed, trashed, and abused. So 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 patio, use a small sledgehammer in order to bash 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 fully-manufactured flashlights may have inflicted upon them.

The tint is not a 100% pure white, but has a very slight pinkish tinge to it.
This pinkish tint is not obnoxious by any means, but it can be slightly noticeable if you aren't expecting it.
All in all, the tint of light is a somewhat warmish white - warmer in color than your typical bluish-white high-powered LEDs.

TEST NOTES:
Product was purchased on the DealExtreme website on 08-05-08, and was received on the morning of 08-22-08.

Product was almost certainly made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.
