4X 18W=150W E26 LED Light Bulbs 2500lm Daylight Energy Saving Spot Lamp COC

Description

About this item
BRIGHT & EFFICIENT:
Compared with other LED bulbs, SANSI's E26 led bulbs can provide SUPER BRIGHT 2500 lumens using only 18 watts of power, equivalent to 150W incandescent bulbs. Based on 3 hours per day usage, consume an average of 87 percent less power, resulting in a lot of cost and carbon savings. Only pay .29 per year.
FLICKER-FREE:
Adopting high light transmission optical lenses, up to 96 LED chips can not only provide you and your family with the light source they need daily but also provide a healthy living or work environment. No flickering, no noise.
PATENTED CERAMIC TECHNOLOGY:
SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, directly soldering the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, making SANSI's bright white light bulbs perform with higher luminous efficacy.
SAFE AND RELIABLE:
The 150 watt light bulb body is made of special ceramic, which is a green and environmentally friendly material, and the flame retardant grade reaches grade V0; the reinforced insulation structure means no risk of electric shock, its safer; the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable and durable; the hollow design is good for heat dissipation.
GUARANTEES:
ETL listed, quality and safety verified, 22.5 years LED bulb lifespan, 2-year warranty. Considering the lifetime, replacement and efficiencies in any cost of ownership calculations, SANSI LED light bulb is a better way.
Potential major adverse effects of flicker identified in published research and/or Expert Opinion include these five factors:
Photoepilepsy or flashing-light induced seizure.
Stroboscopic effect and associated apparent slowing or stoppage of rotating machinery.
Migraine or severe paroxysmal headache often associated with nausea and visual disturbances.
Increased repetitive behavior among persons with autism.
Asthenopia, including eyestrain, fatigue, blurred vision, conventional headache, and decreased performance on sight-related tasks.
