Try Mouser at www.mouser.com or at http://www.mouser.com/catalog/621/437.pdf They have 10K, and 25K at 25 watts or 50 watts adjuatable. Maybe get a 10K fixed at 25 watt, and series with another 10K at 25 watt adjustable. If you can tolerate 25K this is a one piece solution for $11.61 + .29 twice for mounting ears. mouser is a Fast shipper!
