How I can connect two LED lights up to 4 size D batteries?
I want to connect 2 LED lights for my 4 D-size batteries The batteries are "Energizer, 2500mAh, D size, Ni-MH, 1.2 V, rechargeable batteries." I would like the LED lights that lasts at least 8 hours. What are the bright LED lights that need to make this happen?
Ok has 4 x d. You did not say how they are connected in series or parallel. So I take that are connected as a flashlight. Would be 4 x 1.5 vdc. It has 6 volts. As will be super bright LEDs that can operate at 6 volts. 2 LEDs to work long hours with cells d. But start looking at Ni-Cd and solar. You can get unlimited if you just put the pencil to it.

Promised Land [CD-ROM] Queensryche’s follow-up to the double-platinum Empire is something of an acquired taste, but it’s well worth the effort. There’s considerable variety here; the heavy progressive-rock of “I Am I” and the ballad “Bridge” were hit singles, but there’s also the funk-inflected “Disconnected”, the edgy, spooky “Lady Jane”, and the piano-and-vocals “Someone Else?”. The title track is probably the stronge… |
