Finally, one for the beam makers

“With as much as 700 lm accessible at max present, the XP-P allows tighter beam angles and for much longer throw distances than any earlier XLamp LED. XP-P LEDs are constructed to final in excessive functions, with excessive working temperature limits and wonderful sulphur resistance,” in response to the corporate.

Headline figures are:

• 3A and 11W max
• 700 lm max
• 127 lm/W max binned efficacy (at 25°C ANSI)
• 3.1Vf at 1A
• 115° viewing angle
• 150°C max junction
• 2.3°C/W resistance

Ahead voltage is oddly all specified at 25°C. Typical values are 3.1V at 1A (3.5V max), 3.25A at 1.5A, 3.37V at 2A and 3.58V at 3A.

Color bins are all on the chilly finish: 5,000 (described as ‘impartial’), 5,700, 6,000, 6,500 or 7,000K.

Then there are three flux bins, binned at 1A: 360 – 380, 380 – 400 or 400 – 420 lm.
