I added a Jaxman E2L (with default optics) to the comparison, just for further reference. I slightly decreased contrast of the images to let better examine the beam patterns.
Additional experiences:
Color rendering is lovely, to say the least. Some greens/yellows seem to be a little bit less outstanding comparing to what I have experienced with 5700K or 5000K 219C emitters, but the deep oranges and reds are literally popping out - I have never seen anything like this even with 219Cs. Cyans and deeper blues are also very good. On turbo, the light tint acquires a very slight additional purple/deep blue punch. While that is not bad at all, I still prefer to use the level one below turbo.
Regarding the low Vf: I can use a Panasonic NCR18650B button top in the emitter replaced light without any problem to get the most of mAhs out. While I noticed dropped lumens at turbo with the stock emitter even around 3.85V, I just checked the battery to read 3.46V, when I still didn't notice serious lumen drop (was able to fill the battery with 2335 mAh charge then).
I examined the stock optics, and had to admit, that there seem to be no serious flaws regarding optical efficiency, just because the emitting area is bigger, the candela/lumen ratio dropped further. I tried to find out, that the supplied optics whether has 45 degrees beam angle, or 60 degrees, but it is hard to tell, as there are not really any hard boundaries in the beam. Regardless of that, I will look for, and purchase optics with 30 degrees or less beam angle, just for any cases I would need bigger throw capability :-)
UPDATE 180517:
For those pre-orders the High CRI Tiara C1 Pro (and some Wizard), please be patient. Iām still in the making. Below is one of the problem Iām facing:
Precise drill those VR16SP4 was not as easy as I thought. The ultra hard ceramic dulls my HSS-Co end mills in a single pass!
Question about Nichia 219B SW45K R9080 & SW40 R9080
Do you guys think there are still demands for these LEDs? If yes then Iām thinking a committed group buy at reduced BLF price to get the last of itās kind. These LEDs are discontinued already (you wonāt find them at Nichiaās website anymore).
I tested the single E21A 2000K output. I assume this is the same D160 bin Clemence has for sale on his site and not the lower D140 even though it didnāt quite reach 160 lumens at 700mA. The emitter has seen some hard driving though.
Itās D160 rated. The same LED as in the store. It has the thickest phosphor layer off all E21A. High CRI in candle CCT light comes at a price - very low efficiency.
That 157lm at 700mA still within the margin of error. D160 rated at controlled 25C Tj.
This is inline with Djozz built using the same 2000K E21A
Has anybody shaved/de-domed a 219C 5000K R9050? How is the tint (yellowish/greenish?)? I have had a few of them laying around for my Noctigon Meteor for a while now, but Iām not so sure. It currently has de-domed 219B-V1s with 5000K. They are quite nice, but very inefficient.
Clemence, I need to say a big thank you again for these E21A emitters, and your additional serviceā¦ and I think, that I need to be a completionistā¦ :partying_face:
I just finished two more Skilhunt H03 emitter board swaps - one of them had a heck amount of glue among the threads, so it was nearly impossible to get that battery tube loose, but absolutely worth it.
The sm203 gives the perfect ājust before sleepā tint, and it will be very useful for not losing dark adapted eyesight. Probably I will take the chance to order one of the new rechargeable (RC labeled) Skilhunt H03s to check that if I could perform the same actions, because I will definitely need this tint, when I am out in the field for watching meteor showers (or other activities, when only a powerbank is available as battery runtime extension), for taking notes.
The sm403 gives a little bit more complete color perception compared to the sm503, but bluish colored objects become somewhat less pronounced. This tint gives a very relaxing reading light.
I would like to ask if you consider adding the sm453 tint to your emitter lineup, because mixing tints would give more rosy result, and this emitter family seems not to be āsufferingā from being too greenish/yellowish. Based on Maukkaās measurement, the sm503 is a rather a 5300K one, so the sm453 could be a(n almost) perfect reference-worthy neutral white (not counting in the Optisolis, which has currently limited power).
- Thereās a problem with E21A R9080 production for these CCTs: 2000K, 2700L, 3000K, 3500K, 5000K, 5700K, and 6500K. So theyāre not available until further notice. Only < R9050 available, and Iām not going to order anything less than R9080.
- Plenty of sm403 and (normally hard to get) sm453 both in R9080.
- I ordered small quantity of 144AR sm453 R9050 and the special 144AR sm563 R9080.
