Always hear people say LED consumes less electricity. If I am using the track light with 4 LED at 5W each, am I using 5W or 5W x 4= 20W?

Should be more, because you have not measure the wastage from the driver. Give or take 5-10% for the driver, reall good driver with correct voltage usage can have minimal losses of 5%. Cheapo China branc can have 10 to 15% losses. |

I want to ask what sort of bulb I need to buy for my exterior fence and wall light?
The bulb that came with it blew within a week when i only turn on 1hr for 3 days. I changed to Osram but that also blew..My electrician came and said because both top and bottom in covered, the bulb burnt easily. He said need to buy better bulb but didnt say what type or what brand or anything.. Can somebody tell me which type of bulb and brand they use if they have similar type of light or just recommend a bulb that I can try.. Attached image(s) |

Use the CFL or LED bulb. Incandescent bulb cannot last long. Specially with voltage fluatuated.
