The Hera Lighting Elite EL/LED/22/4000/XL is an 21 inch, 4000K (cool white), 7.5 watt LED undercabinet fixture with an integrated LED driver. It is a direct replacement for the Hera Lighting ES22/BC fluorescent fixture. The EL/LED/22/4000/XL is the perfect solution for an easy upgrade to LED from the fluorescent Slimlite XL. This product uses the same connecting and power cables as our SlimLite XL T4 and T5 allowing for an easy retrofit. The EL/LED/12/4000/XL uses half the energy of T5 fluorescents with the same brightness and more than twice the lifetime.
