Though Philips introduced the bulb at a high price at, currently they are sold at $22.99 in Amazon. The price may look high but it saves energy in the long run.
From Phys.org article:
“For $25, or even $35, the bulb looks like a good investment compared to an incandescent bulb. It uses only 10 watts of power, meaning saves about $8 per year in electricity if it’s used four hours a day. It’s expected to last at least 30,000 hours, or 30 times longer than an incandescent. At four hours per day, that’s 20 years.
But the Philips bulb is not only up against $1 incandescent bulbs. CFL are nearly as energy efficient. They use about 15 watts for 60 watts worth of light. They’re much cheaper too, typically costing around $5. The Philips bulb looks odd too -the light-emitting surfaces are yellow when the bulb isn’t lit, yet shine white when it is.
The Philips bulb has some advantages over a CFL: It lasts three times longer and gives off a more natural-looking light. It doesn’t contain the toxic mercury vapor inside CFLs, which creates a minor hazard when they break.”
The LED bulbs last more than 20 years and have no toxic mercury content compared to the CFL bulbs, whose life is about 10 years. The energy usage for both these bulbs are good but the LED bulbs consume less energy (6 to 8 Watts) compared to CFL (13 to 15 Watts).
When CFL bulbs were introduced, I switched all of the bulbs in my home, the energy use dropped $20/month on an average. With LED bulbs I plan to switch, I can expect a longer life and see more drop in the energy costs and don’t have to worry about the toxic mercury content.
You can purchase these bulbs in Amazon.
Also, check the comparison between LED bulb vs CFL bulb vs Incandescent lamp, the savings are huge for LED bulbs. http://www.designrecycleinc.com/led%20comp%20chart.html
