I know this is OT, but there is sufficient genius here that I'd take a stab at this.
So the latest project is for a home where some rocket scientist remodeled it (pretty well, actually), but failed to put a wall switch in the laundry room. This is roughly a 10x10 area with the lamp (a standard hallway style glass dome) more or less centered on it with a pull string. This is untenable for the homeowner when it is dark.
I've tried the eSenLite - in fact two of them - and they have the same defect - the delay timer to shutoff simply does not work. It either shuts down after a few seconds or stays on for many minutes - the middle adjustments don't work.
So - ideally - what I need is something that will fit into the existing fixture as a bulb that will turn on- and off, strictly based on motion, not ambient light. Failing that, a quality fixture replacement is not out of the question.
Ideas?
