What type of solar cell/battery for a garden lamp? Answered
I was looking at an instructable (https://www.instructables.com/id/Solar-Powered-Light-Graffiti-Projector/) involving a garden light hooked up to a red led instead of a white one. It shoots a picture out at night onto a wall or something like that.
I'm wondering if the garden lights are too dim or don't charge fully. We used to have some lights of those type, but they would make a dim light for about 5 hours, then emit a very very weak light. I'm thinking about just buying a trickle charger from here, then getting a bright green or blue led, batteries, and waterproofing it. The problem is, I have nil knowledge about solar chargers/what voltage to use.
Can anyone help?
