LED Chip 50W COB Chip LED Lamp 220V
Right after the receive of two purchased chips, I have provided the usual measurement with proper Wattmeter. The results were very good because both units were rated as having 50 Watts, but in fact, presented 55 Watts, what is very good. No bad surprises, this time. The average life time of these chips, at least for me (with moderate use), is anything around 1 year and a half, even with exceptional heat dissipation device. I hope that, this time, it lasts a little bit more. I love such kind of chip, because they do not need any kind of transformer.
