LED Replacement Bulb 302LM Led Conversion Kit for 3 4 5 6 C/D Cell Mag Lite Flashlights Torch Upgrade

So, the pictures didn't show the bottom of this, I just saw a chrome cylinder - then I removed the lens of my Mag Lite, lifted the reflector out (don't touch the shiny part, or the inside of the glass - you'll drive yourself nuts trying to get the fingerprints off - friendly warning).Next, you remove the retaining nut, which is a chrome tube that screws down to secure the bulb into the base. Lift the old bulb out, and this bulb fits perfectly within the cylinder walls and drops back into the same place the old bulb was. Replace the retaining nut - and don't do like I did and look at the LED when you hit the button. Yeah, you'll see spots for awhile.The old bulb lit up, and it was fine for walking along a sidewalk at night - THIS is way more than the old bulb could ever hope to be. I was thinking "just 300 lumens". I'm guessing my old bulb was pushing around 50 lumens.The circuitry is kind of the unsung hero. Whether they are using pulse-width technology, or a charge pump, or a constant current/variable voltage supply design - I'm not sure. What I do know is that this will drain the last bit of energy from your batteries, and I mean that in a very positive manner.Normally, your battery voltage drops - the bright light becomes dimmer over time; until it's too dim to be useable and you replace the batteries - even though the batteries may have 50% charge remaining. That's a lot of charge to go to the landfill. Using one of the above designs - which are built into the bulb, you not only get more light - the batteries last about 2x as long, and you drain the batteries of all useful life.I'd call that a good win

My old 3 cell MAG-LITE had the original bulb. After buying several new tactical LED flashlights I decided to upgrade the old MAG-LITE with this LED conversion. Very impressed with how bright the light is and how well the beam narrows down. Well worth it and it is now my go to first flashlight.

Made my maglite into a torch

I can't predict how this LED bulb will perform over the long run (it arrived yesterday) but it fits well as a replacement bulb for my 3 D cell Maglite flashlight and using last night I can say it delivers a medium strength adjustable beam well. Since the LED bulb appears well built and solid I expect it to work for a long time and if I remember to update this review to 5 starts in the near future I'll do so after using for a month.

Okay. So, I'll start with what you really want to know. Yes, the reviewer who stated that these bulbs are the brightest bulbs available for the 3 Cell D Maglite was correct and being honest. Yes, these bulbs are abnormally bright, as compared to any incandescent bulb you may have used in the past, and are, therefore, suitable for the ever annoying, but necessary, purposes of finding things in the trunk of your car or under a seat or under the sofa or in the scary and creepy and dimly-lit garage and, most importantly, for the purpose of standing the flashlight on end, up a table where it will be safe to leave it wedged between books or piles of papers, such that the flashlight can and with this bulb will actually be able to light a room, when the power company has failed to warn you of a planned neighborhood outage. I bought this bulb immediately after my flashlight bulb quit on me, during a "planned" yet undisclosed outage and it arrived two days before they "accidentally" shut the power off to the area for an additional four hours, at night. This bulb lit up the entire living room and allowed me to get some work done while waiting and it stayed lit without any interruptions or flickers for the whole four hours and stayed relatively cool. My old bulb was an LED replacement that was too warm and too dark and experience flickers. The CREE bulb has really impressed me. I know, I shouldn't be this excited over a flashlight bulb but showering in the dark does actually still kind of scare me, even at my advanced age, and this bulb didn't even have trouble in a steamy bathroom. This is the same flashlight, with no difference but the bulb, so the bulb is a good bulb. Good luck finding what works for you.

This led bulb is light years brighter than the old incandescent bulb. Great purchase a happy camper.

This bulb is a much better replacement for the original bulb.

Fits and works as expected in a traditional Maglite, 3 D-cell flashlight. This LED is much brighter than the original incandescent lamp. It can be focused into a spot or broad area much like the incandescent.I also bought the Holoson 3-lamp set (3 watt lamps) for comparison. Very similar brightness. Since I have two of the Maglites, I did a side-by-side. Interestingly, the quality of the focus pattern varies with the combination of lamp and flashlight. Minute differences in LED placement may the reason. Another reason to consider the 3-lamp Holosons and experiment.I will try to get some pictures to post.

Haucht der alten 3D Maglite neues Leben ein. Deutlich heller als die Glühlampe. Der Lichtstrahl lässt sich sehr klein fokussieren. Beim Defokussieren enststeht, ebenso wie mit der Glühlampe, eine eher ringförmige Abstrahlcharakteristik.

20年ほど前に購入した３Ｄ（単１Ｘ３本）のＭＡＧライト。十分に明るいと思っていましたが、近年のＬＥＤライトに比べると流石に暗い。。。純正のＬＥＤモジュールを探しましたが、どこも品切れ、取り扱い終了で見つからず。とりあえず純正以外で３Ｄに使用できるＬＥＤモジュールということでこちらを購入しました。本来の性能を発揮するには６セルの９Ｖとのことですが、定電圧電源を使って４．５Ｖ～９Ｖまで変化させてみましたが、特に輝度の変化は感じられませんでした。（正確には明るすぎてわからない^^; ）３セルでも使用できるということは、おそらく定電圧・定電流回路が組み込まれているのでは無いか？　と勝手に判断しております。取り付けは特に問題なく、純正球と入れ替えるだけ。電球単体で比べてみると若干ＬＥＤの方が光源が高く、ソケット側への光がカットされるので配光に不安がありましたが、全く杞憂でした。照射光も粗悪なものは青みがかって、かえって暗く見えますが、この商品はちょうどよい白さで視認性も良好。ほとんど車が通らない夜の道路で、約50ｍ先の反射案内板と5ｍ先のセンターラインをビーム、ワイドで照らし、比較してみました。流石にＬＥＤは光量があるのでビーム状態では反射板からの反射光が凄い！　しかも純正球ではほとんどわからないセンターラインや路側帯のラインまで照らしています。ワイド状態でもその差は明らか。真っ白な光が広範囲を照らしてくれるので、実用性が格段に向上しました。ただし、それなりに発熱はあるので耐久性は不明。ＬＥＤチップの発熱がどれだけ放熱されるか？ですが、このあたりは装着する器具の構造に左右されるかもしれませんね。

They are easy to fit and improve the luminosity dramatically. When you need light they are what you need. They are a little expensive but if you have old maglights they give them a renewed life. I haven’t tested them for longevity but hopefully they will last

This led conversion arrived before its promised date and was installed in the flashlight yesterday. It seems to work very well - I don't have the equipment (light meter) to measure lumens, but as a subjective opinion, the led bulb is far brighter than the incandescent bulb that it replaces. The packaging was impressive for this little bulb and it arrived in good shape. So, although I can't comment at this time on the durability of the product, I am to-date completely satisfied with the purchase. It's installed in a 3 D cell Maglite.

The bulb arrived promptly (within 2days). It was very easy to install, taking approximately 5mins. I would recommend popping some grease or WD40 on the screw threads of the torch before putting it back together. My maglite must be over 30 years old so was a little stiff to open. The grease eliminated the tightness.I use my torch when walking the dog in winter months. It is the 3cell version. This bulb has TRANSFORMED my torch!! The bright white beam is VERY POWERFUL. I managed to eliminate the black spot in the middle of the beam by slightly twisting the head of the torch. This gave me a perfect direct beam that also included a useful surrounding glow. The distance of the main beam was impressive too.WARNINGBe careful if you are using your new bulb/torch in public (like I do, walking the dog) pointing this beast in a persons/animals face will cause instant temporary blindness at short to medium distance. I don’t turn mine on now when near a road just in case any oncoming traffic get dazzled. I never had to worry about this issue with my old incandescent bulb.I never thought I would ever pay this kind of money for a bulb!! I’m glad I did. It was probably cheaper for me to buy another torch? But I couldn’t bring myself to dispose of my trusty well made sturdy maglite. I’m hoping that the bulb will last the test of time? I’ve only been using it a week so I can’t comment.Overall, I’m very happy with my purchase. Thanks
