I am useing Syska LED bulb 14W from last one year and I felt that the light of this bulb is very cool and bright as this light is very suitable for studying and it’s light is spread out into the whole room and the most important part of this bulb is that it is energy efficient which provide nice light at low cost . If the bulb is used for long duration of time but even after that it is not heated much and we can touch it easily. It will not break even if it falls. But only the negative part of it that it is a bit high in cost but it has good quality and advantages.
