Can I calculate what my lumen output will be using a Hatch LED Emergency Driver?

While all Hatch LED Emergency drivers are compliant with the requirements of UL Standard 924, it is ultimately the responsibility of the designer/specifier/fixture manufacturer to assume the system delivers code compliant path of egress illumination in accordance with federal, state or local municipal requirements.

Use the below calculated lumens to help validate your fixture/installation plans in accordance with applicable life safety codes governing your project.

 

Part Number

Rated Output Power Fixture Efficacy Calculated Lumen Output*

ELC08-1248-UNV(-C)

8W 100Lm/W

800 Lumens

ELC12-1248-UNV(-C) 12W 100Lm/W

1200 Lumens

* ELC Units are constant current products. Adjust output power based on LED load accordingly. W = V x I

 

Example: You the manufacturer have a 50W fixture and the LED load requires 25V to operate- you intend to use the 12W ELC Emergency Driver. Select rotary dial #3, 24-36VDC, 330mA; 25V x 330mA = 8.25W. Therefore, calculated lumens on a 100 Lm/W fixture using the 12W ELC emergency driver would be 825 Lumens. Always make sure to confirm adequate lumen output for your specific application needs.

** When operating at ≤25°C, rated output power drops to 4.6W on the ELP05-UNV and 10.6W on the ELP12-UNV.

 

Example: You want to use the ELP12-UNV-K (12W) with a fixture that has an efficacy of 98 Lm/W. 12 x 98 = 1176 calculated Lumen output. Always make sure to confirm adequate lumen output for your specific application needs.

 

Kits can be installed with any fixture in the field or factory as long as the guidelines are met in the installation guide and proper steps are taken to ensure adequate lumen output.
