Bright light and is compatible with my good flashlight that uses two D batteries.

Great LED Bulb

walmart.com

I ordered the Dorcy 30 lumen LED bulb to use in my Maglight 2D flashlight. Installation of the LED bulb was as simple as replacing the old bulb. The beam from the flashlight is MUCH brighter with the LED than with the old bulb. The beam is still focusable like it was with the old bulb. My Maglight uses 2 "D" cell batteries. I use Duracell batteries that are rated at 15,000 mAh. The old incandescent bulb that was in the Maglight drew 670 mA. That gives me a projected battery life of about 22 hours with the old bulb. With the Dorcy LED bulb, I found that it drew just 122 mA. I should get over 5 times the battery life with the LED bulb. Only time will tell if this all works out like the math or not, but I'm convinced that the battery life will be significantly better just based on the current draw numbers I've measured.
By the way, I ordered the Dorcy bulb using Walmart's "Free Pickup" option where they ship to your local store. I paid $4.99 plus tax for the bulb and NO SHIPPING. I just picked it up during my next trip to Walmart

Made my Maglight brighter and use less battery

Very pleased with the Dorcy LED lamp. Brighter than a bulb and works consistently

Dorcy LED flashlight bulb...

Had a few old c and d cell flashlights converted to LED.  They're brighter and use up less power so my dry cells should last a good long while.

More light,less power

maglite with led addition

I have been slowly replacing most of my flashlights' incandescent bulbs with these because they lengthen battery life considerably.

Some things to consider:
Although they are bright, they may not give as much light as the incandescent bulb they replace.
They usually give a broad flood beam, not a concentrated spot beam.
Since they only work with the current flowing in a particular direction, they will not work in a flashlight that applies negative voltage to the bulb center contact.
You may be able to get around this by putting the batteries in backwards.

Only drawback - I think they cost too much.

Lets batteries last longer

I use my two AA cell flashlight for walking and like the slide switch that is easy to operate with one hand when doing so. Additionally, the light has some sentimental value since it was a gift from my wife a couple of decades ago. But, I wanted the greater luminescence and battery life offered by LED lighting. This Dorcy bulb was perfect for that purpose and a simple replacement as well.

Perfect substitution.

Got this to replace the 3V PR4 bulb in an old power failure flashlight (turns on if power goes out).  It was dim but it did work.  This bulb plugged right into it no problems and is much brighter.  Very happy with that part.  The only bummer is can't use it in power failure mode anymore as this bulb dimly flickers when the switch is in the on position while plugged in.  I guess the circuit was designed to take into account the load of the old bulb.  But it will still be a great rechargeable flashlight.

Great little bulb.

I purchased one of these bulbs in November 2015 and was very happy with the results.  Last November it cost $4.99.  This time it only cost me $3.22.
My previous purchase went in a Maglight 2D flashlight.  See my review from Nov 2015 for details.  
This bulb was used in an Energizer Model RC250 Emergency Rechargeable Flashlight.  The emergency flashlight uses two NiMH 1.2VDC batteries in series with a total capacity of 200 mah at 2.4VDC.  The incandescent bulb in the flashlight used 250 ma of current, so it would drain a fully charged battery in about 48 minutes.  The Dorcy 30 lumen LED only uses 65 ma of current, so I should get 3.8 times the battery life.

Increased battery life a big plus!

Works great on old yellow dim flashlights . 
works like new .  the beam is much brighter and farther than the old bulbs .
