I’m interested in a heat treated Nichia 219b version with 18650 tube (assuming the 18650 tube is also heat treated). If the 18650 tube isn’t available with heat treating I don’t want heat treating on the S41S.
With the overall bias towards selecting Nichias so far in this ‘Feeler’, and considering the obvious enthusiasm for the pair of Jaxman HiCri Nichia offerings in 4000k and 5700k, substituting the Cree with the cooler Nichia, or at least testing the audience by questioning their preference could be very interesting. Even better, imagine the audacity of including a 219C in the mix.
A clever manufacturer could perform a comprehensive market test of 4 Nichia options, with or without the Cree if they wanted to in a ‘Feeler’, settling on the most popular for eventual ‘general’ distribution.
