Okay, so i have come to a decision... I think. After pricing out some of these motion sensors and comparing that to the value of my house i have chosen a less expensive route. Not to mention if i purchase the sensor and it doesn't work the way i want i could be out $120.
Let me bounce this idea off of you guys.
Use the standard Cooper motion switch three way but mount it in the ceiling on the back side of the closet header.
Wire it to a three way switch on the outside wall next to the closet and the 3 lights. The switch would only be $20 plus the $1.50 three way standard switch.
Also i would run into the problem of using CFL bulb as the motion switch states that it will not work with them. Would Dimmable CFL's work even if it states "will not work with CFL or elctronic ballasts? I have only found one motion switch that says it will work with standard CFL's but it is a no-name brand.
If all else fails i can resort the incandescent globes.
