Lamp Life
The lamp life represents the average number of hours when the illuminance drops to less than
50% of its initial value under the following conditions with specific optical system. The nominal
lamp life at 160W is (2000) hours. USHIO will continue its lamp life measurement.
♦ The lamp must be operated under the proper temperature condition.
♦ The lamp must be operated on the USHIO’s lamp driver.
♦ On/Off cycle: 2 hours on, 15 minutes off.
♦ Ambient temperature should be room temperature (about 25℃)
♦ Illuminance should be measured on the specific optical system.

Attention for handling
♦ Do not touch the lamp until it has cooled completely, because the lamp is very hot
during operation and immediately after turned off.
♦ The lamp has to be fixed firmly to the base or socket.
♦ Turn off the power supply during maintenance.
♦ Do not hold the lamp except outer surface of the reflector.
♦ Wear protective gloves and eyeglasses when handling the lamp.
♦ Any unusual shock or vibration to the lamp should be avoided.
♦ The lamp contains the mercury. Its breakage might cause mercury to flow out of the
reflector. Please manage provision at the customer’s product.
♦ Do not pull the lead wire and plug by more than 24.5N.
♦ Please be careful of handling the lamp because it is made of glass.
♦ Please notice for keeping or handling the lamp, because there is a projection of this
lamp with reflector ahead.
♦ Do not touch the bulb and the mirror area of the reflector.
Attention for use
♦ Do not close or cover the lamp with any flammable stuff.
♦ During operation, the lamp is under extremely high pressure. Please manage
provision at the customer’s product to prevent fragments of bulb and mercury from
flowing out of it. If the lamp bursts in case of an emergency, the sound will be occurred.
♦ Lamp operation should be with the specified lamp driver and the system ONLY.
♦ Do not look at the lamp directly during operations.
♦ Do not expose your skin directly. We recommend to you to put on something for
protection for your skin. For example, long sleeve shirt, gloves, glassed and so on.
♦ Do not modify the lamp and never use a lamp that has been modified.
♦ Any unusual shock or vibration to the lamp should be avoided during operation.
♦ Do not use any broken lamps.
♦ Dispose of used lamps according to your local instruction.
♦ Do not turn on the lamp while the system is opened.
♦ The lamp contains mercury. If the lamp bursts during operation ventilate the area
sufficiently to avoid inhaling harmful mercury fumes.
♦ Use the lead below 200。C to prevent a deterioration of cladding clad of the
fluorocarbon resin.
♦ The lead wire insulation clad shouldn’t touch the reflector.
♦ Exchange the lamp that has already passed the life time immediately.
