Interlight is a family-owned and operated business established in 1990, with a history dating back to the 1960s when it began with the invention of TV vacuum tubes. The company specializes in providing a vast inventory of specialty bulbs and batteries for various applications, including medical, government, education, and aerospace industries. Interlight offers a wide range of light bulbs from top manufacturers like Osram, Philips, and GE, prioritizing quality by not distributing unknown brands. They ensure quick order processing with same-day shipping for 99% of orders and offer international shipping and drop shipping services for resellers and dealers. Despite its reputation for quality, Interlight has faced criticism for substituting bulbs with different brands and temperatures without clear indication, leading to customer dissatisfaction and negative reviews.
