This should enable the MK-R series to finally provide direct no-hassle replacements to popular form-factors such as MR-16 spots and incandescent lighting in general. The LEDs are sampling and it is stated that "production quantities are available with standard lead times". Reaching a 1600 lm luminous flux light output these LEDs should bring a bright future indeed.
