Led Bulbs

What this episode covers

LED bulbs are the next generation of “green” lighting technology. The Handyguys talk about how LED Bulbs compare to CFLs and whether they are really friendly to the environment. What is an LED bulb? LED stands for Light Emitting Diode. LEDs have been around for a long time but only recently have become effective in lightbulbs. They use little electricity and can last a very long time. LEDs (the diodes) are very small elements that must be combined to produce one bulb that has an equivalent light output needed for a bulb. In addition to the diodes there must be electronic circuitry to control them. Advantages of LED Bulbs Energy Consumption – The energy consumption is similar to that of CFL bulbs and much better than incandescent bulbs. Dimmable – This is awesome, See a demonstration in the video. This is a huge advantage over a CFL. Instant on – Truly instant on unlike a CFL. Its just like the real thing 😉 Long life – between three and ten times the life of a CFL. Color – Great color temperature that matches perfectly with the old incandescent bulbs. Safer – No mercury. Did you know CFLs have hazardous materials in them? Disadvantages of LED Bulbs High initial cost – Prices vary. $30 and up is typical. Some home centers have some for $40 and $50 depending on the style and light output. Shape/style – The initial LEDs have odd shapes and look a bit weird. We expect things to look more conventional as time progresses. Reliability – We do not know much about longterm reliability yet. Is there a cost savings? Lets do some math CFL LED BULB Cost of each bulb $10.00 $31.00 Actual Wattage Used 15 Watt 12 Watt Number of bulbs to be replaced 1 bulb 1 bulb Electricity cost per year (12¢/kWh) $3.94/year $3.15/year Bulb Lifespan (Continuous use, manufacturer supplied value) 8,000 hours 25,000 hours Actual lifespan (when used for 6 hours/day) 3 years 7 months 25 days 11 years 4 months 30 days No. of times the CFL needs to be replaced during the LED bulb’s lifetime 3 times – Total annual cost(Cost of bulb(s) replaced in a year + Electricity in a year) $6.68/year $3.15/year Time for the LED bulb to hit the break-even point: 5 years 11 months 14 days Total savings with the LED bulb(After 11 years 4 months 30 days): $19.25 Conclusions There are a lot of ifs and assumptions to consider such as whether an LED will last its rated hours, will their price decrease and prices for energy. If energy prices stay stable then eventually an LED will pay for itself. Right now its not a compelling case. Saving $20 over 11 years is just too hard to justify for such a big initial cash layout. If you decide the move to LED Bulbs is right for you we recommend buying your LED Bulbs online . Prices are a bit cheaper online, from us, at Amazon.
