4-1. Selling Point Descriptions
4-1-1. Rotary hooked handle

The Model UB 18DSL has a hooked handle. It can be hung on a pipe up to 50 mm (2 inches) in
diameter and locked in eight positions in increments of 45°.
(Locking position: 0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°)
NOTE: When hanging the Model UB 18DSL on a pipe 30 mm (1-3/16 inches) or more in diameter ,

turn the handle to any position other than the 0° position and then hang it on the pipe. It is
impossible to hang the Model UB 18DSL on a pipe 30 mm (1-3/16 inches) or more in
diameter when the handle is in the 0° position because the lamp cover contacts such a
pipe in the 0° position.

4-1-2. Detachable reflector

The Model UB 18DSL is equipped with the reflector to increase brightness and to prevent
backward glare. Use the Model UB 18DSL by detaching the reflector depending on applications.

4-1-3. Holes for attaching a strap

There are two holes for attaching a user's strap at both sides of the upper portion of the handle.

4-1-4. LED small light

The Model UB 18DSL has a white LED that can be operated for about 150 hours when using a
fully charged 3.0 Ah battery. The LED can be lit for a long time because it consumes low power
while it has high directivity. The Model UB 18DSL is convenient as an all-night light if so bright
light is not required.
* The LED will be dim by the

overdischarge protection circuit of the lithium-ion battery if the battery

is nearly discharged

.

4-1-5. Automatic LED switching function

The Model UB 18DSL automatically switches lighting from fluorescent lamp to LED when the
battery voltage is decreased to about 14 V to prevent from being extinguished suddenly.
* When switched automatically from fluorescent lamp to LED, please charge the battery
because the remaining battery level is low.
