Some years ago, before LEDs were a thing, I bought an Ultrafire WF-500 Flashlight that features a Xeon light bulb. As you might imagine the bulb reached its lifetime and burned away.

Now a replacement bulb is available here https://www.ebay.com/itm/321916301663 the thing is that it will cost me 35€ and for that price I could just buy a new LED flashlight.

Now I was considering trying to adapt a generic LED bulb like this one here https://www.aliexpress.com/item/1005002419159094.html?mp=1.

Anyone else with this model of flashlight succeed at a similar mod? Any LED bulb recommendations? Or… is there any other source for the original bulb at a lower cost?

Some photos:

Thank you.

    The reflector of the flashlight is built so light coming from a very small source (like the filament of an incandescent bulb) is directed forward in a focused beam.

    I agree, but I also think that using a modern LED with a single source of forward-facing light is fine. However the emitter would need to be properly positioned in the light.

    Here’s a very similar host (from one of the best low-cost flashlight makers) showing a properly aligned LED and reflector:
