These work well and are drop-in replacement for traditional D-cell Maglites. Seem about 4X brighter - maybe more (subjective). very bright even with old, measurably dying batteries. Focus is slightly disturbed, but since Maglites are adjustable, no big deal. very white light (high Kelvin scale) for better or worse. Worked in all 4 of my lights. Review: Good for 3V, great for 6V flashlights - not meant for 6V lantern batteries or 2x NiMH batteries - I used one of these bulbs to replace the old incandescent bulb in a 3V (2x Alkaline D cell) flashlight. The LED is brighter, whiter, and more efficient than an incandescent bulb. The LED draws 0.11A (1/3W) at 3v and produces considerably more light than the old incandescent which draws 0.36A (1.1W). So the LED is more than 3x as efficient and both the bulb and batteries should last longer even though the light will quit before the batteries are fully depleted. The main thing to note here is that at 3V, these are 1/3W lights, not 3W. However, they are still an upgrade over incandescent. Another important thing to keep in mind for flashlights with only 2 batteries is that 3V is near the lower limit for these bulbs; mine stopped working entirely around 2.4V so these bulbs are not for use with 2x NiCd or NiMH batteries; they require at least 2x alkaline or lithium batteries. I used another LED bulb to replace the incandescent bulb in a 6V lantern battery flashlight. I had to do some surgery on the flashlight (see photo) because lantern batteries have their polarity opposite what's needed for these bulbs (the center post on a lantern battery is negative but needs to be positive for the LED bulb). Fortunately, it's easy to solder wires to the bulbs so I reversed the connections. At 6V, the LED lamps draw nearly 0.5A (3W); the same amount an incandescent bulb draws so the battery life should be the same. The LEDs are *much* brighter; really really bright - I'm still seeing spots, so they are definitely more efficient. My main worry in the 6V lantern is that the LED bulbs will overheat. Dissipating 3W is challenging and the reflectors in most flashlights are plastic so they won't sink much heat. However, at least for short on-times, the LEDs are incredibly bright with 6V and my hope is that if they start to overheat, they will reduce their power consumption by dimming rather than by failing. I'll post the results either way. If you decide to use these in a lantern flashlight that uses the big rectangular-cube lantern batteries with the two spring contacts on top, be aware that the center post of the battery is negative (not what the LED bulb needs) so you'll have to reverse the wiring. Fortunately, the LED bulbs are easy to solder wires to so I cut off the contacts that normally connect the batteries to the bulb in this flashlight and soldered wires instead to reverse the polarity; it worked like a champ. ## Features - LED Bulb for : DC 3V 4.5V 6V, perfect replace for 2-4 C&D Cells Flashlight, NOTE: This led bulb is P13.5S and PR2 socket, CANNOT match with Mag-Num Star Bi-pin Xenon Bulb Light - Attention: This FLASHLIGHT bulb replacement is ring negative, tip positive, please check your flashlight before ordering! - Color:Nature White 6000k, High Power, Long Lasting - The high power flashlight upgrade bulb is long lasting and reliable, offering an estimated 50,000 hours of use. - Power: 3Watt Bright level: 200LM - P13.5S LED Upgrade Bulb PR2 This FLASHLIGHT bulb replacement , for 2CD, 3CD, 4CD, DC 3V 4.5V 6V, convert most C and D 2 3 4 cell PR style flange incandescent flashlights into bright - QTY: Include 4PCS P13.5S 3W 3-6V bulbs (For3V 4.5V 6V 2CD 3CD 4CD cell) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B2J1455K | | Auto Part Position | Outside | | Best Sellers Rank | #11,218 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #749 in LED Bulbs | | Brand Name | GLGYCB | | Brightness | 200 Lumen | | Color | White | | Color Temperature | 6000 Kelvin | | Customer Reviews | 4.5 4.5 out of 5 stars (709) | | Included Components | LED bulb | | Item Type Name | P135S-3W-3-6V-White-4PCS02 | | Item Weight | 0.01 Pounds | | Light Output Maximum | 200 Lumens | | Light Source Type | LED | | Manufacturer | GLGYCB | | Manufacturer Part Number | P135S-3W-3-6W-White-4PCS02 | | Manufacturer Warranty Description | One year. | | Model Number | P135S-3W-3-6W-White-4PCS02 | | Operating Life | 50000 Hours | | Package Quantity | 1 | | Specific Uses For Product | LED flashlight replacement | | Unit Count | 1.0 Count | | Voltage | 3 Volts | | Wattage | 3 watts | ## Product Details - **Brand:** GLGYCB - **Brightness:** 200 Lumen - **Color Temperature:** 6000 Kelvin - **Light Source Type:** LED - **Specific Uses For Product:** LED flashlight replacement ## Images ![P13.5S PR2 LED Bulb Flashlight Replacement Led Conversion kit 2D 3D 4d Cell Bulbs 3W 3V 4.5V 6V for 2-4C&D LED Bulbs 4Pack - Image 1](https://m.media-amazon.com/images/I/61Hz1Ay4aVL.jpg) ## Questions & Answers **Q: Will these work in the maglight 2d cell battery flashlights?** A: yes, it can work with 2d cell battery flashligths **Q: Will these work in the fulton flashlight mx991/u right angle flashlight?** A: need make sure you socket is P13.5S, and the volt is can not over 6V, then can use, otherwise can not use. this bulb only can use 3V , 4.5D 6V , 2CD, 3CD and 4 Cd battery. **Q: Will this work in the surefire e1e executive elite light?** A: the PR2 LED bulb will replace the incandescent PR2 lamp. However the LED lamp will have a blank spot in the center of the light. Therefore if you are using the lamp for close work, the LED bulb is not a good choice. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as intended *by J***E on February 10, 2026* Nice!
