CH6209 adopt high-quality LED chips, entire light efficiency is up to 80lm/w. 90% energy was saved compared to filament lamp. CRI is higher than 85, enables to represent the objects original bright colors, built-in wide voltage (AC85-265V) constant-current power supply, conform to CE,RoHS,Erp etc. Effective life of whole lamp is up to 35000 hours, which is 30times more than common filament lamp. Conform to EU RoHS requirement, energy saving and low carbon, also no pollution of mercury and UV vs traditional fluorescent lamp. Replace the traditional filament lamp or energy- saving lamp.
