Centennial Bulb, the Longest burning Light Bulb in history
Comments (2)Bulb life can be easily extended by running at a lower voltage in a vibration free environment. The problem is that the light output is also reduced....See MoreLight bulbs burning out prematurely in can lights
Comments (11)If you have a volt meter check the voltage at the different fixtures. Especially at a "cold start situation." We've had CFLs in our cans for years and although they seem to last longer than incandesants they do last 5 to 7 years (I date them with a magic marker when installing). I have called the manufacturer and received a coupon for a replacement....See More1 of 2 security light bulbs keep going out, do i need a new light?
Comments (1)The left bulb always burns out soon after replacement, and if you put the bulb in another fixture it might work there. So the bulb isn't actually burned out if it works in another fixture. Sounds like a loose connection in the fixture. Depending on the price of the fixture, it may be cheaper to just replace it than to have it fixed....See MoreLight bulb recommendations for supplemental lamp light
Comments (6)I think about 20 years ago it was a popular idea that a growth part of a cycle happens mostly in the night and nutrient accumulation - in a day - and a friend of mine dutifully turned the timer in his plant room into intervals of 4 hours light 4 hours dark. It was supposed to increase the growth rate 3 times. After a couple months he said - it didn't make any difference - and quit doing it. Otherwise - we all - plants and animals are adjusted to a circadian rhythm - since we are the product of the evolution under the sun. People who work nights eventually develop sleep problems... probably the more complicated the organism - the more important it is - and green one cell algae very possibly is happy to have it 24/7. Humans who live above the polar circle- buy heavy draperies to close their windows to prevent sun waking them up too early. AVs - I cannot say anything definite - until somebody will run the experiment - 24 hours in one room and 12/12 in another - with the same care otherwise. I am sure somebody did - but not necessary on AVs. It can be plant dependent. The plants in Alaska thrive on long hours of the summer - sub-equatorial Africa - day and night intervals are even through the year. People use 13-15 hours per day to stimulate growth and bloom for the show, so it works to some extent....See Morejakkom
