This lamp is fully compatible with the Ultravation UltraMax AS-IH-1001 OEM lamp which sells at a much higher price. It measures about 12 inches, including the 4 pins at the end of the lamp. This specially designed lamp has a unique base specific to Ultravation air filtration systems. Its peak output is at 254nm (UV-C) for use in Ultravation air purification systems. The rated useful life is 9, 000 hours.
NOTES: The sleeve covering the lamp increases the diameter to 7/8 inches. In some older systems, this diameter is larger than the cutout into which the lamp must be inserted. If you have one of these systems, we can supply a lamp without the sleeve. If your lamp has a ceramic cap on the end, it will be about an inch longer. This does not affect the performance or compatibility of the lamp. The lamp is used in UVPhotoMAX EZ-Light or EZ4X-Light upgrades, UltraMAX UME-Series, UltraMAX Gold, and UltraMAX EZUV systems including many of the UMX, UME, UVE, UVS, Photronic and Catalyst systems.
