Due to the pains-taking efforts of R&D engineers for past months, the newest C37 products with innovative ceramic socket have dissipated more heat and become more secure by replacing unique fortified glass.  When the shell of LED C37 bulb is broken, it will not spread over as ordinary glass shell.  Most importantly, the new C37 bulbs remain the same level of illumination as the old ones while its CRI could be as high as 90 and its efficiency might be up to 90 lm/w after repeated lab tests.  At this stage, Civilight schedules to launch the new C37 in April. All the innovative efforts have brought the LED indoor bulbs into new stage.
