The days of incandescent light bulbs are few and far between, and by January 1, 2014, most of them will be phased out. A 60 watt bulb consumes three times the cost of a similar LED bulb each year. Preliminary results from the latest consumer report (ConsumerReports) show that the brightness of the latest and cheapest LEDs is very bright.
All affordable bulbs and new products that have been tested by consumers have the same brightness and brightness as the ones marked, and the color of the light is consistent with its label. Some even offer in-store rebates, so that the price of an LED light can be as much as $10. Keep this in mind when purchasing LED bulbs: Luminous flux display brightness and Kelvin values ​​are critical to determining the color of the light emitted by the bulb.
Consumer reports suggest that consumers should be cautious because there are expensive bulbs on the market. Here are some of the cheaper LED fixtures that impress the experts:
For a 60-watt alternative light source, Wal-Mart's GreatValue white light LED, which costs $10, is the cheapest new light bulb ever reported by consumers, emitting warm yellow light similar to an incandescent light bulb. Cree's 9.5-watt warm white LED bulb costs $13, while the Philips 11W soft white LED 424382 costs $14. The most well-tested Samsung 60-watt warm white LED is priced at $30 and offers bright, warm yellow light. EcoSmart's 14-watt soft white LED 726558 replaces the 75-watt bulb, although its light is warm, but the brightness is better, priced at $ 35.
In preliminary tests, Wal-Mart's GreatValue Soft White BR30 lamp provides high-brightness light and is dimmable, but it is the cheapest, for only $16. The fully tested FeitElectricBR30 dimmable LED, priced at $18, replaces the 65-watt bulb and provides warm yellow light.
In a preliminary consumer report, the $40 MAXLITE20WattPAR38 provides bright white light for use with some electronic timers, photocells, and motion sensors. The fully tested TCP17WPAR38LED floodlight, priced at $40, is said to last for about 46 years if used for three hours a day.
