Is the mercury used in these lamps harmful to the human body?
The mercury used in these lamps is an inorganic mercury compound. Generally speaking, inorganic mercury compounds are not easily absorbed by the human body. However, mercury vapor is harmful in any form, so if the lamp is broken or ruptures during use and any mercury vapor is inhaled, consult a physician immediately.
What is the state of the lamp when lit?
Mercury vapor in lamps emits strong light, reaching temperatures of about 750 degrees C inside the bulb, where the vapor pressure climbs to levels in excess of 20 atmospheres.
Is lamp performance affected by mercury adhering to the lamp's electrodes or the sides of the bulb?
When the lamp lights, any mercury adhering to the electrodes or sides of the lamp enters a gaseous state, and thus has no effect on performance.
Is there a limit to the number of times the lamp can flash?
Each lamp has a rated number of flashes. This is because the lamp may not light if the rated number of flashes is exceeded during the warranted service life. The number of flashes can be determined by referencing the specifications. Use this number as a guide. If the number of flashes is not clear, contact your sales representative.
Tell me about the lamp's warranty period.
Lamps have a warranted service life of 5 years from the month of manufacture. If the month of manufacture is not clear, check the specifications or contact your sales representative.
What should I do if I accidentally touch the lamp with my hands or if the lamp becomes dirty?
Clean the lamp by gently wiping the surface with a soft cloth moistened with alcohol (isopropyl alcohol).
How should I hold the lamp while carrying it?
Carry the lamp by gripping the it firmly by the base and holding it vertically with the anode (the large electrode inside the lamp) at the bottom. For details, see the instructions provided with the lamp.
What causes lamps to rupture?
The bulb of the lamp is made of silica glass, and if the glass is scratched, stress exerted at the site of the scratchy the bulb's high internal pressure can cause it to rupture. Furthermore, if the lamp is used long beyond its warranted service life, cumulative thermal strain can result in lamp rupture due to its high internal pressure.
