Hi Tony, Have you come accross, or heard about, an LED tunnel light? I wonder if it's technically feasible? Regards Ray

I have not heard about or come across LED tunnel lights. A tunnel lamp should have some kind of beam pointed at the tunnel roof to avoid dazzle. LED lamps are made up of a number of LEDs spread over a large surface area so making the production of a beam difficult. The other thing is that by definition the tunnel lamp is used when the engine is running so its consumption is covered by the alternator. I do not see that minimising consumption is a material consideration for such lamps. LEDs MAY give a longer life but I doubt the longer life would be cost effective given the premium charged for LED lamps. In my experience the metal parts of the lamp often fail before the bulb.

Oh dear, not only is the link given "not found" but when you wade through the UNPRICED website you find this thing requires 90 to 120 volts AC. It also gives a beam angle of 70 degrees vertical and 120 degrees horizontal so my comment about the lack of beam control seems fair. Maybe fine for those digging the tunnels but unless it costs less than £15 to include the inverter to provide the 90 to 120 volts this is NOT a tunnel lamp as understood by canal boaters.
