Hey folks this is my initial testing of the Cree XP-P, i don’t have a lumen tube so i am doing what i can to measure output in different ways.
I bought two Cree XP-P from Cutter both are on 20mm T-Pads both are U5 bins, the XP-P i am testing is the 5700k the other XP-P i bought is NW 5000k.
Cree rate the XP-P at 700 lumens at 3amps, in my testing i got 750 lumens @ 4.5amps but that is inside a light. Throw is better than the best XPG2 dedomed but output being only 750 lumens is a tad down, if compared to a XPE its a whole new level.
I tested the Cree XP-P in a C8 using a Convoy 20mm 5 amp driver and a high drain cell, after checking if it would burn out with a low drain cell first lol. The XP-P tested at 4.5 amps max current for a whopping 750 lumens.
First look Cree XP-P left and Osram KW CSLNM1.TG
The XP-P looks happy at about 4.3-4.5 amps
!!
I measure the lux at 5 meters indoors and i took the average of the 3 readings which was 8130 lux @ 5m 203250cd
The three reading are as follows
- 7750 lux a @5m = 193750
- 8540 lux @ 5m = 213500
- 8110 lux @ 5m = 202750
- Average 203250cd
Tress are 150m away
For comparison i have a C8 with the SFT-40 and you can visually see the throw difference i ttesed this C8 at 169kcd and 2400 lumens
