As a manufacturer, we aim to use the top performing LEDs in our LED strips and modules. We are particularly focused on mid power LEDs, those that usually use less than 0.3 Watt of energy, are fairly small and require minimal or no cooling. A big share of our products use these LEDs.
Before choosing the best performing LED for our products we have compared more than a dozen models from the top LED manufacturers: Nichia, Osram Opto Semiconductors, Samsung, Philips Lumileds, LG Innotek, Seoul Semiconductor, Cree, Everlight.
For a meaningful comparison we selected LEDs that function at 65 mA with a voltage between 2.75 and 3.2 V, classified in three groups:
- Cold White (5000-6500K), CRI 80+, for linear fluorescent replacements (LED tubes) or lighting fixtures for the office or industry
- Warm White (2700K-3900K), CRI 80+, usually used in LED lamps, linear lighting fixtures, cove lights, desk lamps, usually for residential and hospitality sectors
- Warm White (2700K-3900K), CRI 90+, with applications in luxury lighting, professional linear lighting fixtures, cove lights for commercial and hospitality sectors
For each category we compare the luminous flux and luminous efficacy at the usual junction "lab temperature" of 25ºC and at a more realistic 100ºC. The comparison data is that from the manufacturers datasheet.
We also added the performance data of average 5050 and 3528 LED packages because such LEDs are still used by many lighting manufacturers today, with applications including linear led modules, fluorescent tubes, lamps, panels or even luxury lighting fixtures.
Cold White (5000-6500K), CRI 80+, for LED strips and modules for the office or industry.
Nichia 757G LEDs have the highest performance and efficacy at 25ºC and 100ºC, with 37.5 lumen and 210 lumen / watt and 33.75 lm and 189 lumen / watt respectively. They also have the lowest performance difference between "lab" and "reality" operating temperatures, at only 10%.
