I don’t think there was much feedback before about a lighted switch being a priority. There was some about aux LED’s.
Also, the current button on the D4 has a pretty good feel as it clicks - much better than the lighted button on the ROT66. I don’t have a Q8 to compare to. Either way, if fitting LED’s on the relatively small button of the D4 adversely affects the feel of the button, I’d vote to keep the better feeling switch.
Lexel, do you/could you offer a replacement D4 driver board like that? If so, I’m very, very interested, both for the original D4 and this new variant.
The stock battery tube on the D4 is quite thick. I think there is room to bore it out for a larger cell without increasing the external dimensions of the light.
I must agree, a 21700 D4 would be awesome. On the other hand, I always wanted the D4 to be a little bit slimmer, close to the level of the FW3A and ZL SC64. 18350 tubes are perfect for impressing people too.
This looks like a better option than the (apparently?) cheapened FW3A SST-20 I ordered last week. I’ll definitely be picking this up when it releases. I appreciate seeing a product improve and not regress in quality!
I don’t own a D4, but if it’s like the D1S (which I do own), Hank likes to keep things tightly packed (as shown below, source). A smaller spring would probably need to be something like one of Blue’s smaller BeCu springs or the tiny one from the Qlite drivers.
I heard someone who ordered a D4 recently got one with programming pads. If I had to guess that was probably the new driver meant for this light. If that’s the case you can probably rule out 3 channel FET.
That + a recessed button (to reduce pocket activations), and my planned FW3A order (which I’m holding on due to the glass screwup) become D4v2 orders instead.
This looks like a good replacement for the FW3A I never got because it was lost in shipping… It’s going to be nice with the features from the D4S but slimmer and easier to fit in a pocket. A 21700 tube would be nice too if it can be made to work.
