Looking for a flashlight

[raybun]

I need a small hand held led light where a vacuum probe could be run out through the center of the lens. This would be used for finding leaks in various chambers using a smoke generator. Thanks

I have not seen a light with such a hole in the middle but there might be something that works. I know that you can get light guide wires, an optical fiber attached to a lens cap. That might work if you attach the output end of the wire onto the probe to provide light.

How small and how bright does the light have to be? You might be able to attach a 1 AAA light to the probe if there is enough space.

Thanks for the idea. Flexible light guides are an interesting idea. I am thinking that if they are flexible enough, 4-5 of them could be bundeled around a stiff tube connected to the vacuum sources. Thanks for pointing me in this direction.
