And perhaps the best example of those wonderful diodes taking over old products is everyone’s favorite light saber stand-in, the flashlight.

LED tech has taken over much of the flashlight market, and it’s not hard to see why.

But there are still other choices on the market besides LED, so let’s look at what makes this tech so special and examine the range of products available.
