Amalgam Germicidal Ultraviolet Lamps – Enhanced Output
STER-L-RAY® Enhanced Output Amalgam lamps provide germicidal ultraviolet output three or more times than that of conventional germicidal lamps of similar length without sacrificing efficiency or lamp life.
STER-L-RAY® Enhanced Output Amalgam lamps are the highest expression of ultraviolet lamp technology and as such are the subject of ongoing technical development and improvement. Custom and proprietary designs are available to satisfy specialized needs. Available in Low Ozone and Ozone Producing versions.

Other sizes are readily available. Custom lamp lengths can also be supplied. Please contact us for help with your needs. Please note that ozone output is subject to considerable variation due to conditions under which the lamp is used; under many conditions, the ozone output may be only a fraction of the specified figure.
(1) Wattage is lamp watts only and does not include ballast loss.
(2) Ultraviolet output at 254 nanometers at 100 hours and 80°F (approximate).
(3) Microwatts per square centimeter at one meter from lamp.
(4) Approximate ozone output in grams per hour under favorable conditions. Figures apply only to ozone producing types.
