Mid Power LEDs performance comparison test: Nichia LEDs in first place

As a manufacturer, we want to use the most powerful LEDs in our LED strips and modules. We focus especially on mid-power LEDs that typically consume less than 0.3 watts of power, are fairly small, and require minimal or no cooling. A large part of our products use these LEDs.
Before selecting the most powerful LED for our products, we compared more than a dozen models from leading LED manufacturers: Nichia, Osram Opto Semiconductors, Samsung, Philips Lumileds, LG Innotek, Seoul Semiconductor, Cree, Everlight.
For a meaningful comparison, we have selected LEDs that operate at 65 mA with a voltage between 2.75 and 3.2 V, divided into three groups:
Cold white (5000-6500K), CRI 80+, for linear fluorescent lamp replacement (LED tubes) or luminaires for office or industry.
Warm white (2700K-3900K), CRI 80+, is normally used in LED lamps, linear luminaires, cove lamps, desk lamps, normally for residential and catering applications.
Warm white (2700K-3900K), CRI 90+, with applications in luxury lighting, professional linear luminaires, cove luminaires for the commercial and gastronomic sector.
For each category, we compare luminous flux and luminous efficacy at the usual "laboratory temperature" barrier of 25ºC and more realistic 100ºC. The comparative data are those from the manufacturer's data sheet.
