30 Lumen 3-Volt LED Replacement Bulb Flashlight Bulbs LED Torch Flashlight Bulb with 10 Year Lifespan, 41-1643 (3)

These are only 30 lumens, and I believe the rating is pretty accurate. These are designed for an 2-cell flashlight (AA, C, or D) that uses a PR-style bulb. They will not compare in any real way to a modern tactical light, or even newer generation LED lights from Mag-lite or other brands. However, they will make older lights much more useful. I have been replacing blown bulbs in several lights, mostly industrial (yellow and black plastic) lights that are for work or emergency purposes. These are great for that, since they are a direct replacement, and require no modifications. The emitter is also well-placed for these lights, and works well with the reflectors, providing a soft center-spot with decent spill. These are perfect for those style lights, or any older incandescent 2-cell lights. Since they are more efficient, batteries will last longer. Some tips: If the light will be used occasionally - such as an emergency light, I would go with Energizer lithium batteries, in C or D-cell adapters if needed, since they last a long time, and have a very good shelf life. They also don't leak. That way, if the lights go out, you will have a reliable emergency light ready-to-go for years. These also seem to work well with Carbon-Zinc batteries, which are inexpensive, but don't last as long. Alkaline batteries of course will work, but they will leak if left unattended, so use them for daily (or nightly) duty, and check them often. These are a great solution for work lights, since they are not too bright to cause eye strain, and would be great for plumbers, mechanics, or anyone else who needs to see well at arm's reach. Color rendering is pretty good, but not quite a good as incandescent. They have somewhat decent throw in an old Mag-lite, but I would go with something more powerful if a long-range beam is needed.

Really pleased with these bulbs. I got 3 (having not seen that I could have gotten 5 for just a dollar more). Anyway, all three work and have a similar pattern - nothing out of focus or dark in the center, etc. It has a whiter light than the original incandescent bulb which is what I expected. I'm not sure how well I captured things in the attached photo's - it is just plain hard to take a good picture of lights. One is a side by side comparison - I have two of these old two AA battery flashlights. The original bulb is on the left, this new LED bulb is on the right. You can see how much whiter the light is with this bulb - both on the wall and looking at the flashlight itself. The other two show the old and the new shining on a wall. Similar pattern with the distinct outer ring and the brighter inner area. Really pleased with these LED replacement bulbs. They should last forever really, they should be easier on batteries, and I *think* they will take the impact of a fall better should you happen to drop the flashlight.

I couldn't happier with these LED bulbs. I used then to upgrade my two "vintage' Garrity flashlights. My flashlights are now brighter than I thought possible, with a nicely focused beam. What makes these upgrade bulbs work so well is the placement of LED high up in the clear plastic bulb, in the same position as the the old incandescent filaments used to be. So, the light from the LED hits the reflector where it was designed to work. I'm impressed.

I ordered these replacement bulbs thinking, like LED replacements for home lighting, they would be far brighter, take less energy to operate (thereby extending battery life), and last much longer than their incandescent predecessors. Ordering was easy, delivery was fast, and the bulbs readily replaced those in my battery flashlights. However, they proved to be no brighter or throw a larger swath of light than the bulbs I was replacing, so I returned them (which, thankfully, was also fast and easy). I cannot speak with any knowledge to longevity or how these may allow batteries to last longer, since they were only in use for a few minutes. Seller should show comparative pictures of the same flashlight with an incandescent and LED bulb to highlight any difference a buyer can expect. A better choice is to look for inexpensive tactical LED flashlights, like the ones I ultimately purchased from a local hardware store (initials HF). They give off WAY more light than my old incandescent flashlights, are a more compact form factor, and include a handy 'zoom' feature which allows the user to concentrate light into a narrower or wider beam as needed. I would buy from this seller again, but not these bulbs.

I got the 3 bulb deal. One...now two bulbs seemed to overheat and started to blink and in about a minute it cuts out until it cools off. I'm on the next bulb and will see how long that lasts. Aside from the blink/heat problem is a good working light for 3 volt flashlights. I'm running it in a 2X AA flashlight. Update: first one is now dead and will not light up at all.
