    LED flood light - Battery powered, light sensing

    Sounds good, guys. Thanks for all the advice. I'll look into Arduino. Probably a good idea for me to become familiar with it anyway as I'd like to look into 3D printing for a completely unrelated hobby. Thanks again.

    LED flood light - Battery powered, light sensing

    The two LED's only need ~4V, though. A 12V rechargeable with voltage regulator would still shut off very quickly? I tried to design the circuit myself, but I got stuck at the charging circuit/optic sensor portion. If you think it's not worth the hassle, though, I guess I'll just have to...

    LED flood light - Battery powered, light sensing

    Dimming is not required, but it does actually mimic more closely the spectral pattern of the sun when it sets (opposite of when it rises). Past noon, as the sun approaches the horizon, our atmosphere filters more and more Blue light away due to refraction which causes the visible light to appear...

    LED flood light - Battery powered, light sensing

    Hi, I'm looking to build a Pfr to Pr converter for indoor photoperiodic plants, but don't know much about electronic circuits. I plan to power a few high power Infrared LED's from rechargeable batteries. The LED's would turn on as soon as all the other lights in the room turn off for the dark...
