1 Overall lamp length including standard lamp holders. To find lamp length only, deduct 2-1/8".
2 Wattage is lamp watts only and does not include ballast loss.
3 Ultraviolet output at 254 nanometers at 100 hours and 80ºF (approximate).
4 Microwatts per square centimeter at one meter from lamp.
5 Approximate ozone output in grams per hour under favorable conditions. Figures apply only to ozone producing types. 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.
* Also available in 3 and 4 pin configuration.
