What happens when you put LEDs in the tower lights normally used to signal machine status on a factory floor? In the case of EZ-Light TL50 tower lights, you get a unit that dissipates 2 W instead of the usual 15 W. Devised by Banner Engineering Corp., their water- and oil-tight industrial housings let the units mount directly to machines, while standoff pipe and adapters are available for elevated mounting. Green, yellow, red, blue or white LED colors are available.
