How certain is the lifetime of the Lemnis LED bulbs?
In general LED bulbs consist of large amounts of small standardized LEDs of 3 o 5 mm in epoxy casting. These kind of LEDs have trouble losing their heat, which causes the useable lifetime of only 5000 to 10000 hours. The white light gets more and more blue. Lemnis Lighting developed its own light source which can cool the heat of the chips to the metal frame. The integrated light source is tested in climate rooms and under extreme thermal conditions. Based on these tests a lifetime of 50.000 hours has been deducted, with a 70 % preservation of light. The current light source is now 2 years in production and also 2 years tested. After 17.500 hours it still gives more than 90% of the original light output.
