The TS10 Single LED, IF they use a 519a, has a beam that is wide enough for general use, similar to a TS10 Triple, but with lower cost for less LEDs per light. By using the TS10SG host with a 519a, Wurkkos would not need to produce a new Triple LED mcpcb for the 519a LED option.
The poll does show there is 49% interest in a 519a TS10SG, and also 51% interest for a High CRI SFT25 5700K TS10SG. They are two different products. The poll shows interest in both.
Wurkkos could be serving both market segments with the same TS10SG host, by using two different LEDs.
I agree this is a valuable feature, and Im glad you pointed that out. I had not noticed that the Buck driver Wurkkos is considering, does not have sublumen capability.
The TS10SG does work well with both the small SFT25, as well as with a 4000K 519a. I think Wurkkos would have two good products by using the same host.. They could save money by using the TS10SG for both roles, since they would only use One LED instead of three LEDs. They can also save on LED cost by using Hopthink LEDs similar to the Emisar NTG35, instead of 519a LEDs.
With these two LED size options, SFT25 and NTG35/Hopthink/519a they could build two versions of the TS10SG, one for throw and one for close range. I think their main challenges so far, is they dont have a Buck driver with Aux lights, and as you pointed out, the one they do have access to does not have sublumen.
I think the poll also shows that the SFT25 version has a certain amount of interest, about 51%. The remaining 49% of poll responders are interested in a 519a version. Although the 519a respondents dont all agree on which CCT, the 4000K has the largest interest among the 519a group.
I hope Wurkkos reaches a useful conclusion on which driver and LEDs to use in their new TS10 model(s). I think a High CRI SFT25, Plus a TS10 Single with a 519a/NTG35/Hopthink would serve both user interest groups. The Hopthink/NTG35 LED option in addition to being cheaper than 519a, can have more Rosy tint. imo the Domed 519a tends to have greenish tint. I consider Rosy tint more desirable.
I like the Tint of the NTG35 4200K better than the Tint of the Domed 519a 4000K.
I would prefer the original TS10SG driver with sublumen Moonlight and Aux, over the Buck driver with no Aux and no Moonlight.
The Simplest solutions:
-
I would buy a TS10SG with the original driver and a Hopthink/NTG35 4200K, with a USB-C battery, and HD10 clip.
-
I think a TS10SG with the original driver and a High CRI SFT25R 5700K, with a USB-C battery, and HD10 clip, would also be popular.
