Operational Life :

When radiant energy reaches 50% of the initial energy at 300mA(dc).



  1. Do not subject the lamp to mechanical shock.
  2. Before using the lamp, ensure glass envelope is clean and free from dirt. Envelope may be gently wiped with either alcohol or acetone.
    Caution: the circumference of the glass envelope around the light box is very thin and should be handled with extreme care.
  3. Care must be taken not to touch lamp body with bare hand, as it’s temperature reaches over 200°C during operation.
  4. UV radiation is harmful to eyes. Suitable eye protection must be worn when observing light output.
  5. Since this lamp operates at high voltages, extreme caution is require to prevent electrical shock.
