@Alec_t GRRRRRRRRRRRRRRR

I deleted you post .... I'm trying to get him to think for himself instead of giving an outright answer

always check out prior posts for that sort of thing before responding :)

:confused: What prior posts? I responded to post #1 in a 'Repairs' forum; not in a 'Homework help' forum.

my post

regardless of where it's posted ... it's good to try and help a poster learn by guiding rather than a straight out answer :)

In the spirit of Davenn's post may I ask some questions?
Wwhy you want to know?
How would you measure the power that any lamp is on? Or what power a resistor is on?
Are these the big LEDs as used for illumination rather than indication?
