Gentlemen;
Light is measured in "Footcandles".
When considering this unit, apply the same thought to the output value.
I have a similar one on my ZX-25 mill. $20 at Princess Auto, when they have them.
Actually, it's the second one. Make sure you add safety wires to keep the light from falling when you're getting into a heavy cut. The first light fell off, then got wrapped around the cutter. The switch (different than the one in the picture) got torn off the wires and flew across the room. Didn't see it again for some months.
Safety wires on the replacement do the trick.
