ALD history traces back to 1958, but we now work within a market transformed by LED lighting technology and ASHRAE influenced regulation. ALD is tightly focused on select specialties and offers high-performance lighting & control products that bring real value. Expect ALD to outline “best-of-breed” solutions, quote costs and explain benefits offered. If your preference is off-shore commodity lighting solutions, please expect ALD to refer you elsewhere. ALD’s history, ethical behavior and experienced staff make us a reliable & trustworthy resource.
