    Driver Improvement:

    Over 5 years experience, many customers has problem with these corn bulbs in the current market,and most of the failure can be bolt down to driver problem. We invested a lot to improve the driver, to restore its credit by applying below:

        1) Rubycon capacitor.

        2) PQ3225 transformer.

        3) EMI circuit with built-in 4KV surge protection.

        4) Toshiba Mos, 10A 800V.

        5) aluminum shell for better heat dissipation.

    Lighting distribution:

    With special beam angle, our LED acorn retrofit bulb is able to direct most of the light down to the ground, to cut light loss inside top of the fixture or waste in sky. And that is where we make great difference over the regular straight corn lamps in the market. It is dark sky friendly, more efficient and energy saving !

    Is regular straight corn bulb a good solution for acorn post top lighting ? Think again !

    Lighting applications:

    LED acorn retrofit bulb is mainly for outdoor post top lighting fixtures, acorn lighting fixtures and lantern lighting fixtures with base up MH HID HPS lamp.Such as GE patriarch luminaire,King luminaire,American Nail Plate LA4421 etc. It generate dark sky friendly lighting for outdoor acorn post top fixtures as LED replacement lamps.
