My fiancee's closet has been a notorious black hole, with stuff getting lost in the dark corners of it. I have a 12V battery available to power this project. Before I go buy all the parts, can anyone please confirm that this is a sensible schematic?
I chose a pair of constant-current LED drivers to account for the varying voltage coming from the battery, using a reed switch and MOSFET to switch them, and put the whole thing on a 2A fuse for safety.
The drivers: https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?productId=2006932
The LEDs (three in series per driver): https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?productId=2153166
The MOSFET is your garden variety IRF630 (with protective diode built in), and the reed switch is rated at 0.2A, which I figure should be enough to flip the MOSFET.
I'm not sure if I can put the drivers in series since the LEDs are only 3.4V, or if the driver needs >= 9V to drive them (and would thus need to be in parallel). If anyone has any thoughts on this, or on any other parts of my circuit, please let me know. Thanks!
