Description
G-Light is a rechargeable, cordless, LED curing light. It emits light in the 390-550-nm range, with peaks at 465-475 and 400-420 nm. Light output is reported at 1200 mW/cm2. The unit is the first cordless LED to emit light that can cure materials containing both CQ- and PPD-based photo-initiators. G-Light is silent and fanless. It features continuous and 5-, 10-, 20-second timing options on the back of the unit. A battery life display is also found on the back. If not used for more than two minutes, the power source automatically switches off. Normal charging time for the battery is two hours. In an emergency, a five-minute charge will produce 13, 10-second irradiations. The unit evaluated includes on battery, a battery charger with power cord, and five anti-glare cones. A protective light shield and a handpiece cradle are optional. The cradle has a sturdy metal case with an ergonomic sling-shaped design. Fifteen consultants used and evaluated G-Light over a three-month period for their complete light-curing needs. This product received a 92% clinical rating.
Equipment Features
Approximately two-thirds of consultants who evaluated G-Light were using an LED light in their office. They rated quality of cure as excellent for all bonding agents, composites, sealants and cements used. G-Light is convenient to disinfect and is easily portable from operatory to operatory. Although the unit only comes with one battery, an additional battery pack is available for purchase. The most-liked f e a t u res of G-Light were the portability, quiet operation, ease of activation, and accessibility of the buttons. The least-liked feature was the limited access for curing materials in posterior areas of the mouth. The unit is slightly heavier than many other LED lights, yet is well balanced. Sixty-seven percent of consultants found G-Light to be equivalent to or better than their current curing light. Sixty-four percent indicated that they would switch to G-Light from their current curing light and 77% would recommend it to a colleagueEditors’ Note: The original evaluation was published in THE DENTAL ADVISOR, Vol. 22, No. 10, December 2005.
