Osram has a reputation for producing LEDs that deliver consistent quality and durability. Warm, white light is generally more comfortable. The TIR lens of the Seeker 4 Pro can reduce light loss, it captures and redirects much of the emitted light. The electronic switches may have a higher chance of standby drain.
