New generation of 2200K sodium led corn bulb

9-2

1) Sodium outdoor led light (led garden light, led street light, etc.) is very important in raining or foggy weather, Strong penetration make drive or walk safer. But until today, the color temperature of led bulb is generally 2700-6500K. Make 2200K led light is difficult, needless to say heat dissipation, high temperature rise, high cost of produce, only how to keep high lumen efficiency is a headache to designer.

After many years’ persistent efforts, we successfully developed 2200K sodium led corn bulb, and has been applied.

2) Feature of 2200K sodium led corn bulb

(1) Low color temperature wide beam angle long lifespan

New generation corn bulb successfully make color temperature as 2200K, small size, Side lighting, high light-emitting area, 300 degree beam angle. 25000 hours lifespan.

(2) Detail specification of led corn bulb:
