I opened a Sunwayman V10a
and installed a E21a 4500k.
I then did some comparisons to a 219b 4500k sw45k
first impressions
the E21a 4500k is greener than the sw45k
no surprise there, the difference in duv predicted that (thanks to maukka for the charts)
The e21a seems to make colors pop more than the sw45k
even though the sw45k makes reds redder, and on the e21a reds are more orange
the e21a makes whites whiter, the sw45k makes them pinker
I need to spend some quality time with the light during the day tomorrow, to get a better idea of the tint of the E21a compared and contrasted to the sw45k, during daylight brain balance.
work in progress on the beam from the E21a, there is a ring in the outer spill, and a donut hole within 3” of target… need to lift the mcpcb by 0.5mm
and the centering ring needs to be clearanced over the solder joints on the mcpcb
The E21a board is smaller, which creates the contact of the solder joints to the centering ring.
An easier mod would be an sw45k reflow to the stock board, but I am curious to experience the E21a 4500k.
centering the LED is also a work in progress, again because the e21a mcpcb is smaller and not auto centering…
Im expecting some thermal epoxy, to experiment with, for centering and height control of the e21a mcpcb
Its been a long evening peering through a jewelers visor… time for some quality time online… LOL
I want to thank my mentors, coaches, and other supportive members of this community. I could not have gotten this far without you.

a few comparisons
fwiw, though the tint of the E21a 4500k seems a bit yellow/green, in actual use the color rendering is excellent. imo, People who find the sw45k too pink, will like the E21a 4500k.
