Nowadays, LED lighting has a lifespan of 20,000 to 50,000 hours; in terms of continuous use (in years), equates to 2.3 years, and for 50,000 hours (more common with most LED lights); a huge 5.7 years of non-stop use! That's a lot of years if you only use your LED lights for 4 hours per night, 2 times per week!
Unfortunately, some of you are still happily using your older type of lighting that requires old-style plug-in bulbs. Don't worry; Yowcha stocks a range of old-style bulbs, and UV and halogen lamps!
