SST makes some of the most reliable truck and boat lights on the market. SST's 12V LED lights are made of solid, thin-profile aluminum strips with swivel brackets attached to both ends. Vibration does not cause damage to the LED strip. The LED strip comes on at full brightness at all times and does not flicker in winter. SST will replace the swivel brackets on our lights free of charge.
A typical 18-foot truck would need:
TWO 6.5W, 4-inch strips mounted to its ceiling to provide the same brightness as in a typical residential living room, or
SIX 21W, 2-ft strips to provide the same brightness as in a typical commercial office
Note that SST's strips have roughly the same coverage as a fluorescent tube. SST's thin-profile LED strips are also perfect for shelf lighting.
