Lite Source has been supplying eye care professionals and medical practices for over 40 years. Founded in Louisville, Kentucky, we've grown from a specialty bulb and battery supplier into a full-service eye care supply and diagnostic equipment distributor — while staying independently owned and operated. We are a certified Women's Business Enterprise (WBENC), and we take pride in the kind of personal service and deep product expertise that larger distributors simply cannot offer.

Lite Source specializes in ophthalmic and eye care supplies — including diagnostic equipment, instrument bulbs and batteries, ophthalmic exam supplies, and small diagnostic instruments in the $100–$10,000 range. We serve optometrists, ophthalmologists, and ophthalmic practices across the United States. While we supply other medical specialties as well, eye care is our core focus and where our deepest expertise lies. We know the brands, the equipment, and the needs of eye care practices better than any general medical distributor.

Our company is proud to be located in Louisville, KY since we were founded in 1985. Our address is 13703 Aiken Rd, Louisville, KY 40245-4621.

Lite Source accepts returns on most items within 30 days of purchase in original, unused condition. Returns may be subject to a restocking fee depending on the item and manufacturer. Equipment that has been used or removed from original packaging cannot be returned unless there is a manufacturer defect. To initiate a return, call 800-523-0860 or email us before sending anything back - we will provide a Return Authorization (RA) number and ensure your return is processed smoothly. For our full return policy, visit the Return Policy section of our website.

If products are defective, contact us immediately at 800-523-0860 within 30 days of the original invoice. For manufacturer defects, we will work directly with the manufacturer on your behalf to arrange a replacement or warranty service. 

Accept the package, if it is safe to do so and contact us immediately. If there is any damage to the product due to mishandling by the shipper, do not discard outer packaging. The shipper will not issue credit without inspection.

Yes - all new diagnostic instruments sold by Lite Source come with the manufacturer's standard warranty. We sell only new equipment direct from the manufacturer. We do not sell 3rd party, old or used equipment that would jeopardize the maximum warranty. Warranty terms vary by manufacturer and product. If you have an issue with a piece of equipment that you purchased through us and it is still under the manufacturer's warranty, contact us and we will help facilitate the replacement or repair.

The easiest way is to search by equipment brand and model number on our website - we organize bulbs and batteries by both brand and equipment type. You can also call us at 800-523-0860 or chat live during regular business hours. If you provide us with your equipment's brand and model number and we will identify the correct part immediately Numbers or letters that are printed on the item are also helpful. Our team has 40+ years of experience with ophthalmic and medical equipment and can usually identify the right part from just a model number or description. For more advanced identification, we may ask for a photo of the part.

OEM (Original Equipment Manufacturer) parts are made by or supplied by the equipment manufacturer. Equivalent parts meet the same electrical and physical specifications but are produced by a third-party manufacturer — typically at a considerable cost savings with no meaningful difference in performance for most applications. Lite Source clearly labels all products as OEM or equivalent so you always know exactly what you are ordering. We also maintain strict quality controls around our equivalents and will only supply the highest quality products. As technology changes and manufacturers cease part production, sometimes an equivalent is the only option available. 

Yes - we carry bulbs, batteries, and parts for a wide range of ophthalmic equipment brands including Haag-Streit, Topcon, Zeiss, Heine, Keeler, Volk, Marco, Bausch & Lomb, and many others. Browse our website or search by equipment type. If you do not see what you need, call 800-523-0860 or live chat during regular business hours - we may be able to source it.
