If we all agree on 10440 this would mean to develop a whole new boost driver, consequently an even higher sales price to cover development costs. Moreover, I'm worried that multichemistry support (1.2/1.5V and 3.7V) will be quite a challenge with such a small driver. Are there any big advantages to expect when driven with a lithium-ion battery? 10440s are much more difficult to source as well as quite expensive. Charging these little suckers in a standard li-ion charger can also become a challenge.
Definitely interested if 3 (or 4) mode with sub-lumen and decent mode spacing. Only really interested in NiMH, not bothered if it supports 10440. Iām ok with the suggested tints, however I wonder how popular the 2000K option would be (is 2700K more popular?). If the options were 3500K, 4500K, 5700K I would probably buy one of each.
In case theyāre thinking of different hosts, Iād be very interested if they made a small twisty AA, seems to be a big gap in the market (unless Iām missing something).
Edit: IIRC the max safe amps for E17A is 1A and E21A is 2A (although I could be wrong, will find the post)
Nearly every AAA driver can work with 10440, this is not a challenge but often an unintended feature.
Even the regular C01S oneā¦sometimes: some users reported that it worked, some burnt theirs.
I suppose it needs some minor tweaks, thatās all required to turn this light from nice but dim to a small hotrod.
Thermal design is fine and IMHO itās a shame that such omission limited the lightās performance so much.
Dim lights are not my kind of stuff, regardless of how good the beam is, thatās why I requested this feature.
Okay, if it's that easy what tweaks are we talking about here? How can a manufacturer make sure that the E21A emitter will not get toasted if someone puts in a brandnew Efest 10440? IIRC, the reason why some C01S did not burn was because they used some low drain and/or partly discharged 10440s. Please don't feel offended by my questions but it would be a complete nightmare for a manufacturer to face returns of defective lights in large scale.
Iām in of course. Guess the LED works fine with that driver. 1800K would be very nice, but also too special for mass market. And we know Sofirn has problems sourcing Nichias. More likely they would consider NW tints.
I donāt know. Thatās why I wrote this as a supposition rather than a statement of a fact.
If a LED burns you have a dead light.
If a driver burns you have a dead light.
I donāt see how improving the driver would make the matter any worse, let alone turn it into nightmare.
Now to the also important question, can E21A survive a fully charged, high drain cell? Iām not sure but quick calculations show me that it canāt. Which is a bummer indeed.
I guess few people will care about 10440 support then. Though I still do; even if I kill E21A, a good driver enables me to put some other LED in there. Like SST-20. And I would still have as bright as Iād like.
BTW, thereās one thing to take into consideration when converting a light from SST-20 to E21A. The latter is very flat and may easily have the light emitting surface well below the focal point of the optics.
I like the C01S concept, but Im not a fan of the AAAs. So here is my idea: install the C01S driver (maybe with slight improvements) in the bigger body and make the āC10Sā - twisty AA light, as small as possible, something in style of DQG Tiny AA or L3 L10ā¦No need of 14500 support, AAs with their higher capacity(comparing with AAAs) would be good enoughā¦
Iām definitely interested in the lower temperatures, but not the 5000K - if the highest temperature was around 4000K I would probably get that too.
Iām happy with the C01R UI and NiMH support. Iām not interested in 10440 Li-ion support - I wouldnāt mind if it was an option but I wouldnāt want it to compromise NiMH support.
