That's a brilliant idea. :THUMBS-UP: Once E21A can be ordered, I will talk with Barry to see if a free diffuser can be included.
I'm sure there's room for a small extra discount if someone wants to buy multiple lights. If it turns out that for instance most people want to buy 2000K AND 4500K, well I see no reason to not offer a bundle of both tints for a special price. Anyway, pricing may better be discussed once Sofirn confirms they are able to get those E21A LEDs.
Personally I would avoid extra accessories if they raise the final price.
Anyway diffuser it’s just a plastic cap and it shouldn’t cost more than $0.5
I make some by my self using marker cap or others stuff around home
Replacement lens would be more important for keychain use
