LEDs can also be dimmed as normal

With the instant full intensity of led street light , they are great for rooms/applications where cycling is a factor (turning on and off frequently). Repeated power cycling does not harm or hinder LED light bulbs. On a similar note, LEDs can also be dimmed as normal, albeit by slightly different means; a pulse-width modulator or lowering the forward current.
C. Crane describes its warm white GeoBulb as the first 60 watt direct replacement bulb that uses less than 8 watts. One of the things we like about the GeoBulb is that it is the same size as a conventional incandescent bulb; therefore, it is suitable for direct replacement in any indoor open fixture. In addition, it's one of the few bulbs that we have come across where the manufacturer has published independent lumen test data, so you can have some confidence that it will actually produce as much light as the manufacturer claims - something that, sadly, can't be said for a lot of the bulbs out there.
For people who want to save electricity and money, the LED light bulbs are a good choice. These are available in a wide range of color temperatures. It is the white filament led street lights that produce a light that is similar to the traditional incandescent light that used in general home lighting.
