Hey all!
Got a little project I'm working one with a friend. We bought a dynamo camping lantern which consists of 6 white LEDs connected in parallel. The power is supplied to the LEDs via a few AAA batteries, which are charged by turning the handle. We'd like to add more LEDs to make the lantern brighter.
My physics is a little rusty, so it'd be great if someone could explain why this happened: we removed one of the 6 LEDs, which didn't affect the brightness of the other 5 when it was switched on. We replaced it with a red LED found lying around the house, which caused the other 5 LEDs to dim. We took the red one out and replaced it with the original white LED and it was back to normal. Is the red LED introducing some kind of resistance that the white ones aren't?
Any advice you could provide on this project would be much appreciated - otherwise we'll probably end up destroying the lantern! I suppose the most important thing to know is whether it's possible.
Do these LEDs look any good?

Thankyou in advance!
