What Is Lumen Depreciation And How To Eliminate This
All lighting technologies available on the market from HID and fluorescent to LED suffer from lumen depreciation, the process by which the lumen output produced by the source reduces over life time. Lumen depreciation is dependent on a number of factors such as the type of source used, the operating temperature of the source and the operating hours undertaken. Lumen depreciation varies widely between technologies and is generally lowest on sources such as fluorescent and LED and highest on sources such as HID.
