DC 18V 6-24V Upgrade Replacement Bulb

After a dozen years or so, the 18V incandescent lamp in my Ryobi P700 flashlight burned out. For the added few bucks over a replacement incandescent bulb, I figured I'd give the LED bulb a try. It's a piece of cake to replace. Turned on the flashlight and it lit up perfectly. I had read with interest the review by "Paul" that shows how he tightened up the pattern by adding a 0.065" washer. The pattern I'm getting as-is is very good up close to about 3ft and then there is a slight dark center beyond that. I tried Paul's trick with some washers I had. I didn't have a 0.065 but I did have a couple on either side of this thickness. It did improve the pattern at distance but degraded it for close-up work. In the end I decided that since I usually use it to illuminate parts I'm working on at a couple of feet away, I'll leave it without the washer. Out of curiosity, I put an ammeter in series with the LED bulb to measure the current draw. With a fully charged P103 lithium battery pack on the flashlight I'm seeing 150mA. The original incandescent bulb is stamped 0.6A (600mA). So the LED uses one-quarter of the power of the old incandescent. Thus I would expect the flashlight to operate about 4 times as long before requiring a recharge - cool! BTW, the LudoPam description on the Amazon page tells you to be sure your device is tip-positive (LEDs are polarity sensitive). If you are using it for a Ryobi P700 flashlight like I am, rest assured it is tip-positive and the LED will work.

The Craftsman 19.2-volt flashlight I’ve had in my toolbox for many years came into my possession as a promo addition to a portable power tool kit. It was seldom used having never produced a bright enough light to serve any purpose. Recently wondering if I could convert it to LED illumination, and not having very much hope due to the odd 19.2 voltage, I searched Amazon using the term Craftsman and lightbulb to see what might be available. One of the listings was the LudoPam 18-volt light bulb. Reading through all the listings, this particular bulb seemed to be the one most likely to work with my flashlight.Worked, it did! The shone area changed from being dimly illuminated to a brightly lit. With this simple LED lightbulb improvement, I could now see the area on the underside of my car that needed work. What was formally a near useless gadget occupying toolbox space is now a highly useful flashlight due to a simple lightbulb upgrade.

I looked a few years ago for an LED replacement for the halogen bulb that came with my (very useful) Ryobi 18V flashlight. Didn't find anything, then, but was pleased when i finally found this. It's not bad -- but as you can see in the first picture, the light pattern leaves a dark hole in the center. The picture is from 10'. The hole is present from just a couple of feet away to infinity. But it turns out that if you add a thin washer (mine was .065" thick, just a bit over 1/16") between the reflector and the bulb, the beam tightens up, and you get a nice bright spot. It's been so many years since I had a working halogen bulb that I don't remember what the beam was like originally, but this will do.

I have several heavy duty shop flashlights as part of cordless tool sets and I still like using them. These LED bulbs bring new life to these otherwise excellent units and extend the working time with a charged battery to many, many hours.Easy to install and working great.

Great LED replacement bulb. Very bright, makes the battery last longer, and withstands dropping unlike a normal bulb. I was hesitant to get it when someone said that the light will become a spot-light, but since I use it outside most of the time, it is just what I needed. There may be issues if you try to use it under a sink to see as you work since the light is so focused. To solve that maybe a piece of wax paper over the light to defuse the light?

This is a better light bulb

Works OK and only a few dollars more than a pack of regular bulbs. The light output is a little yellowish in the center with a bluish tint on the edge, so not uniform yellow like the original bulb. But it is WAY brighter and the battery lasts at least 3X as long. The beam pattern is a little worse than the original bulbs due to the shape of the reflector, but the original beam pattern wasn't great anyway.Would I buy again? Perhaps , but I would consider just getting a different flashlight rather than keep the Craftsman.

The bulb burned out in my 18V Ryobi One flashlight. I tried several shops, but no one had a replacement. One shop had an LED replacement bulb that "fits most C and D cell flashlights." I bought one but it didn't work and I returned it. Amazon claimed this bulb would work, so I ordered one. When it arrived, I saw that it was also marked "C and D cell flashlights." I was afraid that it wouldn't work, but when I tried it was perfect!
