   I need help LED home lighting. I need high CRI (90+) GU10 bulbs that are dimmable without flicker (even if I wave my hand in front of them), silent (even to dogs), and either:

   • ~240VAC and work with triac dimmers

   • 24+VDC and work with constant current dimmers

   • 24+VDC and work with PWM dimmers

   Do these exist?

     @mattgrayyes Is there any strobe effect if you wave your hand between the lights and your face while they're dimmed?

     @ryanc I think these are the silent ones I got several years ago

     @mattgrayyes The spec sheets don't say anything about how the dimming works.

     @kim Unfortunately it doesn't look like they do GU10 down lights.

     @ryanc@infosec.exchange My partner has an eye-movement disorder that means she sees stroboscopic artefacts with flicker, and she's sensitive up to about 6kHz.
     
     https://sansiled.com/ were the only manufacturer of traditional bulbs that seems to be consistently good at this, though they seem more interested in industrial fixtures and grow lamps.
     
     (They're much better engineered than the usual supermarket brands: Proper power supplies, decent heatsinking, etc. I haven't noticed any acoustic noise from them, but I haven't held them to my ear to check.)
     
     Not tried their dimmable stuff, we don't have any TRIAC dimmers in the house.
