...Tunnel LED Lighting solutions... TUNNEL LED LIGHTING High power, low consumption public LED lighting Specially designed for tunnel and underground lighting applications, the Joliet tunnel lamp unit offers exceptional performances thanks to high power LED lighting technology. The exceptional photometric properties of Joliet high power LED street light bulbs, in addition to offering a bright, natural light colour, provide a uniform rectangular beam pattern (40x16 meters at 12 meter height) that is 50% brighter and 50% larger than the oval beam pattern produced by a conventional lamp. This highly focused beam pattern allows LED lights to be spaced at much wider intervals than sodium lights increasing still further the savings achievable in initial investment requirement and operating costs.

Tunnel Light details Connections Installation 1. Attach the fixed arm (6) in the required position, space between fixings is 120mm and the diameter of the hole is 10mm 2. Mount the movable arm (7) on the bridge board (9), then lock the M8 nut to fasten the active arm. 3. Fix the bridge board (9) to the lamp body (10) by sliding the 4 M8 bolts into the T shaped runner on the back of the lamp body (10), then put the bridge deck (9) on to the bolts and lock the four M8 nuts. 4. Connect to the lamp assembly to the fixed arm (6) by connecting the regulation bolt (8) then adjust the angle, and rotation as required before final tightening of the adjusting bolts.
Connections 1. Remove the power Supply junction box cover (4) and the sealing gasket (5) 2. Pass the cable into the power supply junction box through the cable fixture 3. Bare 6mm of insulation from the cable ends. 4. Connect the cables to the corresponding terminals and tighten the waterproof cable entry nut. 5. Replace the power supply junction box cover (4) ensuring that the sealing gasket is correctly positioned. COMPARISON BETWEEN JOLIET LED TUNNEL LIGHT AND HIGH POWER SODIUM LAMP Real Case analysis.
