- Products must be de-rated according to the de-rating information. Each de-rating graph refers to

specific LEDs. Please refer to graphs on page 3.

- Luminous intensity is measured at 20mA on a discrete LED unless otherwise stated.

- Intensities (lv) and colour shades of white (x, y co-ordinates) may vary between LEDs within a batch
