1. PRODUCT NAME
Hitachi Cordless Lantern, Model UB 18DSL
2. MARKETING OBJECTIVE
The Model UB 18DSL is a fluorescent lantern that works on Hitachi BSL 14 series batteries.
3. APPLICATIONS
For construction work, outdoor use, etc.
4. SELLING POINTS
LED small light
Usable for 150 hours as an all-night
light (when using a 3-Ah battery).
Holes for attaching a strap
The handle has holes to attach a
user's strap.
Detachable reflector
For increased brightness and
prevention of backward glare
Automatic LED switching
function
It automatically switches lighting
from fluorescent lamp to LED
when the battery is discharged.
* When the battery remaining
power is nearly empty, the
overdischarge protection
circuit may prevent the LED
from lighting.
14.4-V slide-type lithium-ion
battery is attachable.
Rotary hooked handle
It can be hung on a single pipe 48.6
mm in diameter, and locked in eight
positions in increments of 45°. It is
also possible to lock the lantern
upside down.
NOTE: The battery is sold separately.

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.

-4-
5-2. Specification Descriptions
5-2-1. Brightness
The brightness depends on the ambient temperature. The light may be dim if the ambient
temperature is extremely low.
5-2-2. Continuous operating time
Continuous operating time means the continuous lighting time when using a fully charged battery.
It varies in accordance with the frequency of use, battery capacity and other factors. Accordingly,
the continuous operating time values in the above table are intended for reference purposes only.
5-2-3. Specification of fluorescent lamp
The Model UB 18DSL is equipped with a natural (EX-D), compact fluorescent lamp equivalent to
FPL 9W. Use the fluorescent lamp specifically designed for the Model UB 18DSL (code number
323339, model FPL9 EX-D).
5-2-4. Automatic LED switching function
A fluorescent lamp extinguishes suddenly if the battery voltage becomes low. To prevent this, the
Model UB 18DSL automatically switches lighting from fluorescent lamp to LED when the battery
voltage is decreased to about 14 V. Please turn the switch off and charge or replace the battery
immediately.
The LED will be also dim by the overdischarge protection circuit of the lithium-ion battery if the
battery voltage becomes 10 V.
5-2-5. 14.4-V slide-type lithium-ion battery (sold separately) is applicable.
The Type BSL 1430 lithium-ion battery is equipped with the overdischarge protection circuit,
overload protection circuit, and voltage monitoring circuit for each cell to prevent shortening of the
battery life due to overdischarge (overuse) or overcharge (excessive charging) of the battery.
The number of charging/discharging is about 1,500.
Precautions for use of the Type BSL 1430 lithium-ion battery
The Type BSL 1430 lithium-ion battery is equipped with a protective function that automatically
stops output to extend the battery life. The LED may dim automatically when the battery voltage
becomes 10 V even if the switch is set “LED.” This is because the protective function is activated.
The battery is not faulty.
Please instruct the customers on the above precautions.

6. PRECAUTIONS IN SALES PROMOTION (SAFETY INSTRUCTIONS)
In the interest of promoting the safest and most efficient use of the Model UB 18DSL Cordless
Lantern by all of our customers, it is very important that at the time of sale the salesperson
carefully ensures that the buyer seriously recognizes the importance of the contents of the
Handling Instructions, and fully understands the precautions.
• Handling Instructions
(1) Do not touch the fluorescent lamp while it is lighting or immediately after turning
off to avoid burns.
The fluorescent lamp is very hot while it is lighting or immediately after turning off. Wait
until the fluorescent lamp has cooled down before replacing the fluorescent lamp.
(2) To prevent personal injury due to accidental falling, secure the Model UB 18DSL
with a band when hanging at a high place.
If there is a danger that the Model UB 18DSL may fall from a high place, secure the
handle and the pipe with a band tightly. Personal injury may occur if the Model
UB 18DSL falls from a high place.
(3) Always turn the switch off before replacing the fluorescent lamp or when not in
use.
Otherwise, the service life of the fluorescent lamp may be shortened and short circuit
may be caused. If the Model UB 18DSL is left for a long time with the switch turned on
and the battery installed, the service life of the battery may also be shortened due to
overdischarge.
(4) Do not use the Model UB 18DSL in the rain.
The Model UB 18DSL is not water-resistant and a failure may be caused if it gets wet.
(5) Do not shock or disassemble the Model UB 18DSL.
Otherwise, inside soldering may fall off and the fluorescent lamp may be broken.
(6) Do not allow the Model UB 18DSL to contact gasoline, thinner, etc.
The outer frame may be damaged by gasoline, thinner, etc. although it is made of strong
synthetic resin.
(7) Do not leave the Model UB 18DSL in very hot locations exceeding 60° (140°F)
such as the inside of a car in summer. Leaving the Model UB 18DSL in such
locations may cause a failure.
(8) Do not use any battery other than the specified batteries.
The Model UB 18DSL works on 14.4 V and 18 V slide-type lithium-ion batteries only. Do
not use any other battery.
(9) Do not use the Model UB 18DSL with the lamp cap removed.
Otherwise, the fluorescent lamp may be broken.
Others
Store the Model UB 18DSL in a dry place at temperature 40°C (104°F) or less. Remove the
battery from the Model UB 18DSL before storage.
