Comparison of incandescent lamp, energy-saving lamps, LED bulbs

Incandescent, energy saving lamps, LED bulbs compare
    40W incandescent lamp luminous flux 340lm, while 5W energy saving lamp luminous flux 300-350lm around, and now LED bulbs can be up to 160lm per watt or more, but under normal 110-120lm so, perhaps when the LED high bay light technology is more advanced cases next, LED lumens per watt bulb will be higher. So 5W 40W incandescent and energy-saving lamps, 3W LED bulb which is the highest price it?


    Chart table is calculated according to 30000h, from the total purchase cost point of view, Incandescent 30 * 1.8 yuan / month = 54 yuan, energy saving lamps 10 * 12 yuan / month = 120 yuan, LED lamp 1 * 30 yuan / month = $ 30, the total cost of ordinary energy-saving lamps expensive; view from electricity, electricity incandescent highest 624 yuan; LED bulbs lowest 46.8 yuan; total price of the same is the high cost of incandescent and LED bulbs cost minimum.
     Today, LED bulbs prices gradually declined every year, then costs will also reduce, so from a cost point of view, the use of LED high bay light are the most efficient. Just a lot of friends taking into account the initial purchase price is too expensive, but not a long-term considerations, such as the number and use of electricity generated, focus only on the immediate interests. Overall, the most cost-effective use of LED light bulbs. Post by LED panel light finishing, Copyright Austrian a special LED lighting manufacturer!
