UPDATES:
The lenses have arrived! I spent last night swapping the lenses with moshow's XML2 pill, since he was interested in the narrow option. I took a bunch of beamshots with the XML2. I will take N219 beamshots tonight and post everything. Sadly, it appears that the narrow TIRs do not work well with the XML2. the throw is no better than the 25, though the hotspot is narrower. The 8 degree also has some annoying sidespill that I think is inappropriate on a thrower. The readings do show how efficient the 25deg. lens is with that emitter - actually with both emitters. I think the narrower lenses will work much better with the nichia from my limited look - I'll report fully after the beamshots tonight.
For the XML2 5k, the total lumens on high (1.5a) were:
Lens | Lumens |
8 | 415.8 |
15 | 394.2 |
25 | 442.8 |
30 | 399.6 |
45 | 421.2 |
60 | 426.6 |
mule | 394.2 |
bare | 631.8 |
And for the N219 on about 1a:
Lens | Lumens |
8 | 173.88 |
15 | 163.62 |
25 | 189 |
30 | 175.5 |
45 | 180.9 |
60 | 179.82 |
mule | 167.4 |
bare | 288.9 |
jd1911, I'm testing (playing) with yours, and I think you're going to like it. It measures 896lm on high, and 282lm on medium. Low is still moonlight at about 1.5lm (hard for me to measure that low with my meter). so far, no heat issues that I can tell, but obviously you will want to limit the runtime on high and monitor the heat to what your hand can stand. I'm satisfied enough that I'm going to order more 3a drivers and offer them for the XML2.
I'm doing quality control on the 4 that are ready - don't want to release them until after testing.
Thanks.
