Hubbell Replacement Lens for End of Aisle High Bay Occupancy Sensor HBRLEA

Hubbell HBRLEA replacement lens for an end of aisle high bay occupancy sensor. Used to replace a broken lens or to convert the attributes of an existing sensor (from 360 degree to end of aisle, or from low bay to high bay, etc). Features include:

• This is just the replacement lens; it is not an occupancy sensor.
• Fits the following Hubbell sensors: HBS13D, HBS28D, HBS48D, HBS24D, HMHB219, HMHB229, HMHB23A9, and HMHB23B9
• H radius to mounting height ratio is 1.4 up to 30 ft high, and 1.1 for 30 to 45 ft high. I am not exactly sure how the H radius is defined but I assume that it means the detection area of the sensor on the floor when you have this lens installed.
