Is there anyone who could build a copper p60 drop in with a 219b v1 93 cri 4000k ?.
Thanks.
For a solarforce l2d.
I may be missing something here, but what is the difference between the B V1 and 219C, other than the colored pads?
Thank you for all your time testing LEDs djozz!
They are totally different in appearance, so you don’t need to distinguish them from their solder pads. A and B also looks quite different. It’s just the B and B-V1 that look very similar apart from the solder pads.
I hope this isn’t a longshot, but does anyone have some solid beamshots of the “Nichia NVSL219BT-V1 4000K, 93 CRI, D200 Bin” versus the 219C that RMM carries?
I realize this is asking for 4000K vs. 5000K beamshots, but I’m trying to decide on what to get in a triple
I do not have those comparison beamshots, but I think the beam shape of the 219b v1 and 219c will not be very different, so a beamshot will not capture the difference. What is different is the output (the higher the current, the bigger the difference), and the colour reproduction, both is difficult to catch in a picture.
gotcha, thank you sir!
Sorry CD50, missed your post. I find the 4000K clearly warmer tinted than the 4500K. This is also because 4000K is my personal maximum acceptable colour temperature so I’m sensitive in this region. The V1 can easily be run at 2A, especially if you use a ledboard that has a direct thermal connection to the core (DTP, some brands are Sinkpad, Noctigon, Maxtoch).
