As one of its daily deals, Amazon offers Prime members the Sunforce 80-LED Solar Motion Light, model no. 82080, for $29.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $7.26.) That's at least $5 less than you'd spend at a local retail store, although in November we saw it for a buck less. It features a 30-foot detection range and three control dials. Deal ends today.
