I am trying to retrofit an independent light dimming array into a bedroom ceiling fan (Hunter Whittington) because the built-in dimmer and supplied A19 bulbs leave quite a bit to be desired (e.g. the dimmer sometimes decides that your automation specifying 8% brightness from 6AM to 8AM will occasionally decide to just give you 100%).
Ideally this would have proper CCT LEDs (mix of warm and cool white, or dedicated CCT elements) so it can be coupled with adaptive lighting which is especially important to me in a bedroom or office.
There is a device shown here: https://www.elektroda.com/rtvforum/topic3909154.html which looks like the guts would be perfect (thought the size of the array is not mentioned); but I cannot find what the equivalent device would be in US/NA markets.
The requirements for fitting / what the fan can hold:
- slightly over 8"/200mm of space before it hits the glass. Full A19 depth.
- 110V AC L and N in the lighting space (separate L wire at canopy bypasses fan internal dimmer)
- Prefer wifi so I can run a switch with esphome and set up espnow (not afraid of transplanting an ESP-12F or ESP-32; I have a hot air gun). Again, not looking for a ‘dumb’ array because I want to avoid Hunter’s dimmer / flaky HomeKit light control.
- Brighter than two Kasa KL130 A19 bulbs (not too difficult, they are quite dim in my other fan)
The space available (the rectangular section can be unscrewed. It houses the AC mains connectors and the E26 receptacles can be removed with screws/rivets easily):
This should be a simple retrofit, I just need to find the proper donor. I would prefer the light to be CCT; or have a focus on CCT with weak RGB as noted in the above-linked light “RGB colours are not very bright, in other words… disappointing. But CW colours are very bright. Good value for money overall.”
Does anybody know anything on Amazon US or on Ali/Fleabay which would be of proper dimensions internally? The outside dimensions of any light will almost never correspond with the array size if it is of suitable brightness.
Any help is greatly appreciated.
