## Description

Ruiandsion 2pcs 2W COB 3V E10 Base LED Upgrade Bulb Replacement for Flashlights Torch LED Light, White - desertcart.com

## Features

- 【E10 LED Upgrade – See Clearly Without Eye Strain】 That old incandescent E10 bulb too dim for soldering or reading a magnifying glass? This 150-lumen LED gives you clean, comfortable brightness – enough for detailed hobby work or fixing vintage flashlights. Fits 3V, 6V or 12V.
- 【Pick Your Perfect Glow – Cool, Warm, or Yellow】 Cool white (6000K) for task lighting on microscopes or bike headlamps. Warm white (4300K) for that classic dash light or retro radio look. Yellow for soft Christmas bells or address lights. Just match your original bulb voltage.
- 【Polarity Sensitive – Works with Negative Ground Devices】 This E10 LED requires negative ground – the standard for most flashlights, bike lights, and battery-powered gear. If your device uses positive ground (some old radios or early cars), it won't light. Please check your equipment's polarity before ordering.
- 【Cool-Running & Safe for Plastic Housings】 Unlike hot halogen or incandescent bulbs, this LED stays cool. No more melted lenses or burnt fingers. Perfect for lighted makeup mirrors, miniature house lamps, science classroom projects, and holiday ornaments.
- 【Breathe New Life Into Old Devices】 Got an MGB dash that’s too dark? An ancient penlight torch or soldering gun that needs a replacement? This E10 LED fits standard screw bases. No wiring mods – just screw it in and get reliable, long-lasting performance.

## Questions & Answers

**Q: Would this bulb work for a 5 cell flashlight ?  7.5v**
A: I doubt it seriously.  These are like miniature night light bulbs.  I got these to replace the incandescent bulb used in a rock crystal lamp.  Very low light output.

**Q: Are they dimmable (thru a rheostat)?  [Using 3 AA batteries/1.5v]**
A: Lowering the voltage will dim the bulb, tho I don't know how well a r/stat would work ? (on a DC lamp) at such a low voltage, and almost no amps !

**Q: will these work in a 6v lantern?**
A: I ordered this bulb specifically for an old lantern that uses the recrangylar 6v battery.  They DO NOT work in the lantern I have.  The old bulb works so I know the battery is good.  The base is bottoming out as well.  Not sure why it will not work.  Tried both new bulbs as well.
