So many form factors nowadays but I like when it uses disposable batteries in case of emergency. You cannot buy disposable 18650 and the likes. AA, AAA and D are still the defacto common for batteries. They still use it in cameras remote control analog clock etc. You dont want to waste your money buying high end rechargable batteries on your remote. Does this have moonlight. It would be great becaise in an emergemcy where power is down you only have disposable batteries and having moonlight mode is a plus.
