Lighting Products - Whether under the economical glow of a 6-year fluorescent light or the intense illumination of a non-glaring sodium vapor lamp, you are likely to be benefiting from lighting products produced in Harper equipment.

Manufacturers employ our rugged, corrosion-resistant kilns in the reaction of halophosphors for lighting, and color phosphors for entertainment applications.

Many of the high density alumina tubes that form the heart of sodium vapor lamps are sintered in Harper equipment.  Over the years, Harper has worked closely with major international lighting companies such as Phillips, Samsung, NGK, and G.E. to develop and install thermal processing equipment for the new process technologies that have enabled today's advanced products.

Offering superior custom design and extraordinary reliability, Harper reactor and kiln systems have been in use for years at lighting products plants worldwide. And Harper continues to expand its design capability and technology base for the years ahead.
