I have this old 2D flashlight , and I thought it time for a LED upgrade :
So I got me a 3v LED replacement bulb off Ebay .. I mean how bad could it be ?
I must admit this light is old , and some what corroded on the inside , so I was expecting ( not very much )
With fresh batteries I got some ( measured ) 110mA current , which equates to around 0.35 Watts ..
In the light box , the best I could get was 55 Lumen .. It was very difficult to get a steady current reading so please dont bother with the calculator ..
Now the package say's 150 Lumen , so I'm about 100 Lumen down ..
This is a old light , so low current draw with usable amounts of output is a plus .
The beam is not pretty if you can imagine , and a very nice RING is produced that grows quickly with distance ..
Now that I have tried it , would I recommend it ?
Actually No ..
It works , but the design for use with 2D flashlights is very bad .. The emitter simply does not match a Crypton bulb , or any filament type bulb at all ( For transmitting light ) .
The old adage , something is better than nothing , comes to mind .
Looks to be reliable
Outputs decent amount of light
Low current draw ( ? )
Fits all flashlights that take a Crypton bulb ( This style )
Could it work in 3D / C ( ? )
More pictures ASAP:
