Review: Been Wanting LED Replacement Bulbs for the Old 222 Lamps. - I have a very nice vintage lighted magnifier that uses 2 AAA batteries and a 222 incandescent bulb. I also have a nice 50 something Ray-o-Vac pen light that uses 2 AA batteries and a 222 incandescent bulb. I had quit using both because the incandescent bulbs don't last very long and they run the batteries down quickly. These LED replacement bulbs not only fit perfectly, they give a substantially greater amount of light than the incandescent bulbs (I used both, the difference is dramatic). Beautifully white light. Now I'm using these two vintage items thanks to these wonderful LED replacement bulbs. Longer batter life, much longer bulb life. Why would anyone want to use the incandescent 222 bulbs at all? They are truly obsolete.
Review: Very long battery and bulb life. - Lifetime replacement for classic penlight 222 incandescent bulbs. Batteries would last as long as their shelf life, as the current draw is not much more than 10 ma. where the incandescent bulbs draw 250 ma.! Bulbs are expensive as such, but low current draw and extremely long LED life would be saved in battery and bulb replacements. One caution: You may need to reverse the batteries in your penlight as the LED bulbs are polarized, tip positive, screw base negative. In the end these bulbs become an outstanding value, because of very low bulb and battery replacement.

## Questions & Answers

**Q: Would these work in a portable microscope where there is one lithium battery (3v)?  i previously had a 2.5v/0.5 amp halogen bulb**
A: If the base type (E10) and physical size are the same as the original halogen bulb then, yes, they should work. I can't speak about the brightness compared to the original lamp though.  Jim

**Q: For pachinko. how much volts/amps can the take?  got 6v {4 aa}.**
A: They are designed for 2 standard AAA/AA/C/D type batteries which makes 3 volts.  4 cell lights are 6 volts. These will die really fast if you hook them up to anything more than 3.5 volts. If you're looking for an E10, screw in base LED bulb like these, you're best to look at something like these 6 volt types:

**Q: Is the button polarity positive or negative?**
A: I put one into a penlight where the battery positive contacted the "button" and it worked.

**Q: What size and how many batteries do these take? I want to use these on my vintage bicycles.**
A: they need 3 volts to work properly

### ⭐⭐⭐⭐⭐ Been Wanting LED Replacement Bulbs for the Old 222 Lamps.

### ⭐⭐⭐⭐⭐ Very long battery and bulb life.

### ⭐⭐⭐⭐⭐ They're bright!
*by M***O on May 9, 2019*

I got these for an ancient slide viewer whose bulb finally gave up the ghost. Appreciate the comments from others about reversing your batteries if the bulb doesn't light up the first time. The bulb is very bright. The good news is that it illuminates the slides better than an incandescent bulb. The (slightly) bad news is that there's a bright spot in the center. That's an advantage in a flashlight (the intended use), but not great when you want a diffuse and even light behind the slide. But since I'm simply using it for sorting through a large bunch of slides, it's definitely not a deal-breaker. Bottom line: Recommended.
