It might be a good business move to mix 3000k and 4000k LEDs to create the elusive “true neutral” 3500k bulb. There are a lot of sellers selling 2700/3000/4000/5000k bulbs, but I don’t know of any selling a good 3500k.
I know you are thinking I must be basing this on personal opinion, but the ANSI standard “C78.376-2014” accepts 3500K as the true neutral.
Oooo, you should make a ~13W BR30 replacement. Would love to see that 3500k combo in our kitchen!
Edit: Added BR30:
Edit: In fact, the BR30 is even more suited to this configuration for LEDs. The A19 and A21 bulbs are designed to be closer to omni-directional, while the BR30 is designed for a 90 degree direction beam.
Edit2: If I could buy BR30 in 3500K SunLike 2835 that put out 1000 lumen for under $35 ea, I would buy 6 right now.
Thanks Joshk, I use Figma for just about everything that doesn’t need more than 0.1mm precision.

Here’s an (optimized) png of my SORAA VIVID bulb. It’s a bit thicker than normal BR30’s, so I took measurements with calipers in case it helps to find another body that might fit.
SunLike, in a year or two years, with the work you are doing in this area, a company is going to try to buy you out in a way that may well sell you short, or worse maybe just take your work and market with a much larger backing fund.
Here are both options. I like the idea of risers best, since that gives us the ability to have the LEDs at the same depth within the fixture as a standard BR30. The overlays do show that it might still have a clearance issue though. I’d have to get a more detailed diagram of the standard BR30 fixture to check that clearance without just trying to screw something in.
The extender solves clearance, but also has the plane of LEDs 15mm further from the socket.
