Incandescent bulb is not energy efficiency. It will be phased out and replaced.CFL is mercury hazard. Somebody can't tolerate the UV rays generated by CFL.
Why not try LED lights? It's durable and efficint.
Although there still are engineer chanllenge for LED lighting, the cost of LED lamp is high,LEDs really are very efficient light sources.LED spot lightfor task lighting, LED down light for under cabinet lightng, LED strip for cove lighting, LED module for backlighting.
LED bulb has much more benefits than incandescent bulb and CFL. Don't contain mercucy, waste electricity bill.The problem is LED lamp is not bright enough for general lighting. It's expensive.
Because they are efficient and controllable, LEDs are already being adopted by retail outlets and other commercial customers. In the past year, LED light bulbs designed for home use have come out as well, but at significantly higher prices than traditional bulbs.
There are 40-watt and 60-watt equivalent LED light bulbs sold at large retail outlets, such as Home Depot and Lowes, with prices in the range of $18 to about $40. Lighting manufacturers expect prices to go down steadily for the LED bulbs, some of which are rated to last 25 years and are far more efficient than incandescent bulbs. But in the near term, the purchase price will still be higher than existing technologies.
Moving to a cheaper manufacturing process, coupled with ongoing efficiency improvements of GaN, will help push LED lighting into general lighting based on purchase cost, Posselt said. Watkins, the former CEO of disk driver maker Seagate, said the manufacturing technology means LED companies can lower prices faster.
Researchers for years have tried to put GaN on silicon, but there are challenges in making the two materials work together, notably the differences in thermal expansion. One of the common problems is defects or cracks that occur on the chip.
The quantity and quality of light you can now get out of an LED source has really dramatically improved, Now the issue is cost and how to get the cost lower.
Try to replace your fixtures with LEDs. Let there be LED light.
