The Ceiling Lights is entirely free of mercury, lead or other toxic chemicals which are common in mercury-vapor lamps and high-pressure sodium lamps. Because of the long life cycle of these lights there is certain to be a lot less need for general maintenance. This type of light is most practical in places where light bulbs are difficult, inconvenient, or expensive to have replaced.
Even though there are plenty of benefits related to using these LED bulbs, there are also a couple of downsides. One issue that is likely to be noticed from the outset is the high initial expense. Many of these lights can cost over double the price of the more traditional lights. Plus, the type of light is generally limited to directional light, so less effective at providing the spherical "glow" that emanates in every direction. For this reason the lights are more practical for the forward facing or hanging streetlights, and not the lamp style.
