Sunlight Induction lamps from LVD in Taiwan has a circular solution to a troubling problem. Previous lamps that are charged by solar panels usually had 180 degree beam angle at fairly low strength. LVDs solution maximizes the current usage and doubles the lighting area by making a circular globe as opposed to a straight line globe from the past. The result is a 50-90% improvement in both power usage and lighting intensity as well as consistent coloration. The two semi-circle sides are powered from the same point on one side to the same point on the other side, hence doubling the product, but reducing the cost that would normally be involved if you used two globes. These eco-friendly induction lamps are made RoHs compliant (meaning that no heavy metals are used in their production) and with over 80lm/W, the energy saving lights give great long term savings.
