Rosewill Design

Unlike most LED bulbs on the market, the Rosewill bulb has done away with the heavy external heatsink by replacing it with our 3rd generation internal ceramic cylinder. Our new ceramic cylinder design not only offers a more efficient cooling method, it also produces superior lighting emission when compared with regular LED bulbs.

Most LED bulbs have LEDs arrayed in one direction only. This means that light is emitted in a 120-degree radius, resulting in bright illumination in only the front part of the bulb.

Rosewill’s 3rd generation internal ceramic cylinder provides an even 300 degree all around light source.
