A UV dryer for curing multiple surfaces of a product comprises a plurality of UV lamps connected end-to-end to form an assembly having a longitudinal axis. Each lamp includes a tubular envelope aligned along the longitudinal axis. The assembly is pivotable along the longitudinal axis at ± angle from a vertical plane containing the longitudinal axis to direct radiation from the assembly toward a leading, top and trailing surface of the product as the product is moved toward, underneath, and away from the assembly, respectively.

A method as in claim 8, wherein the dryer is tilted ±45° from a vertical reference plane. 10. A UV dryer for curing multiple surfaces of product, comprising: a) a plurality of UV lamps configured into an assembly along a line; b) each lamp including a linear envelope aligned along said line; and c) said assembly is pivoted about an axis ± an angle from a vertical plane containing said axis as the product is moving to direct radiation from said assembly toward a leading, top and trailing surface of the product as the product is moved toward, underneath, and away from the assembly, respectively. 11. A UV dryer as in claim 10, wherein said lamps are configured end-to-end. 12. A UV dryer as in claim 10, wherein said line is a longitudinal axis of said assembly. 13. An apparatus as in claim 7, wherein: a) said at least one dryer being pivotable along a longitudinal axis ± an angle from a vertical plane containing said longitudinal axis to direct radiation from said at least dryer toward the leading, top and trailing surfaces of the product as the product is moved toward, underneath, and away from said at least dryer, assembly, respectively. 14. An apparatus as in claim 13, wherein said angle is about 45°. 15. An apparatus as in claim 7, wherein said at least one dryer includes a microwave powered UV lamp having a linear envelope. 16. An apparatus as in claim 15, wherein said UV lamp includes an elliptical reflector. 17. An apparatus as in claim 16, wherein: a) said lamp includes a pair of end reflectors having defocused positions; and b) said envelope is disposed at said defocused positions. 18. An apparatus as in claim 16, wherein said lamp includes external reflectors.
