Voltarc T12 HO Lamps

Varc’s flourescent sign long lamps for bigger signs or longer letters reduce the number of wiring components, sockets and ballasts, while streamlining the construction process to achieve real savings compared to systems that use conventional shorter lamps. Installing 9 or 10-footers translates into fewer parts, fewer outages and less overall maintenance - adding to performance quality and cost-efficiency. The ballast should carry up to four F108, F117, F120T12/HO lamps - offered by all sign ballast makers. The sign-maker should provide starting aids to help in reliable lamp starting when temperatures are low or humidity is high. For double faced signs, a grounded strip of metal stretched the length of the lamp serves as the starting aid, 1/2" wide and 1/2" away or 1/4" wide, 1/4" away are acceptable. For single-faced signs, the metal cabinet back will normally serve the purpose.
