It has been an eventful few years, but BulbFacts is still testing new products, especially in the LED and Halogen categories. Lifespan testing has continued, new products are being added as requests come in, and the charts and recommendations are still being maintained.
All product re-tests were completed on the 25-foot 2.0 platform and uploaded to the test charts and recommendation pages. New products were used when available so the results stayed as relevant as possible.
