Commercial LED Retrofit Lamps from SLT – German Engineering
Commercial LED retrofit lamps for in- and outdoor HID applications. From 12W up to 30W.
LED retrofit lamps are a good choice under the following circumstances:
- the overall condition of the fitting is still good
- For energy savings and reduced re-lamping labor – upgrading from Mercury Vapor lamps which only have half the luminous efficacy
- For mainly reduced re-lamping labor – upgrading from Metal Halide and High Pressure sodium lamps.
- the different light distribution of the LED retrofit lamps results in a satisfactory illumination
- the geometry of the LED retrofit lamp allows an easy replacement
- the lamp holder can carry the higher weight – additional supports for horizontal operation are available
- the life of the integrated electronics match the life of the LED’s, e. g. 50,000hrs which are 12.5 years for street lighting
WARNING: Old ballasts and Ignitors must be disconnected. Lamps are not dimmable

In order to compare the performance of LED retrofit lamps versus HID lamps you have to consider the following:
Life: HID range from typical 16,000hrs to 30,000hrs, defined as average rated life with 50% of the lamps have failed totaly
Lumen depreciation: Between 50% @ 10,000hrs and 20,000hrs for HID lamps
LED’s: typical and for the LED retrofit lamps above –> L70 @ 50,000hrs, i. e . after 50,000hrs the light output is down to 70% as a result from light output depreciation and/or total failure of LED’s
Lumen output efficacy: for HID lamps between 50lm/W and 120lm/W measured @ 100hrs, LED >100lm/W. Depreciation, see above
