What is the expected life of each bulb in hours?

with constant usage (24 hours a day) they have lasted for about 9 months. Feit electric puts out a 42 watt bulb that produces more lumens (2800 lumens from the feit compared to 2500 from these cheaply made Chinese lights). As I have used these for plant growth I change the bulbs every 6 months, and have noticed that though they last 9+ months running 24/7 the quality of the lights is so degraded its more worth it to buy higher quality feit electric bulbs... plus on top of being cheaply made they get VERY hot (roughly 190 degrees Fahrenheit) and will burn small seedling plants.

I can say i have used one bulb for at least 25 hours and it is still running great

If these led bulbs are like other led bulbs they should last somewhere between 20,000 - 50,000 hours

The average LED light lasts between 25,000-50,000 hours. In figuring this, if you use the lamp for an hour a day, every day, the bulbs will last over 68 years. There is also a 1 year warranty that comes with the lamp. If you would like to email the company, the address is: info@spheregadget.com and a representative will contact you within 24 hours, according to the site. PS...I Love mine!!

The Amazon page I am looking at has an image of the bulb's ratings label, and it says 31.9 years at 3 hours a day. That would likely be about four years full time use since heat is probably not much a contributor with a bulb this small. I suspect they would really last much longer.

On average, LED bulbs last 50,000 hrs which translates to a little less than 6 years of continuous use. Odds are, you're not going to use the light 24/7 so it'll last considerably longer than that. I've been told 25 years, but time will tell. They're very bright. Bought a dimmer switch compatible with LEDs and that solved that.

T5 four foot 6500K fluorescent bulbs. The bulb life is stated to be 1000 hours, and recently four of my six bulbs burned out within a two week period after about that time frame.

I don't know the exact hours on this one. But most of these style bulbs are 250 hours.

On average 5000 hours but then again it all depends upon your viewing also.Bulbs are cheap at $100...well worth it !

Hi, Donald. The bulb is bright and is very energy efficient, however the life is shorter than most standard candelabra based bulbs. It says the life is supposed to be 3000 hours . . . I have purchased three and of the three, two of them lasted less than 500 hours. Pretty pathetic for a bulb in this price range. The electricity saved does not balance the cost of the bulb. In my experience, the lamp is a poor choice.

There is really no way to calculate the expected life. It depends on the type of fixture and, in the case of strings of bulbs as in landscape lighting, the distance from the transformer. Lamps closer to the transformer will not last as long as those further away due to higher voltage and the initial surge when they turn on.

From what I have read the bulb life is 5,000 hours.The cost for new bulbs are about $200

Thanks for the info. I hope to goodness that the lamp life is not 3,000hrs! I've been waiting years to buy a projector that doesn't require rip-off bulb replacements. My own HS201 is on a UPS truck at this very moment, waiting to be delivered to my house...

LEDs should be good for 100,000 hours of use. If you left the lamp on continuously (which you won't), that's over 11 years. By then, I doubt you will be looking for replacement LEDs for this (by then) obsolete lamp.

I think you meant to ask about the life expectancy of the bulb. Tthe life expectancy of the LED bulb is 100,000 hours

If you are asking how many hours the bulb is rated for, then it's 3,000 hours I believe. 4,000 on eco mode. I have about 500 hours on mine.

RESET the bulb timer in GENERAL SETTINGS>LAMP REPLACEMENT. This should have been done when you put the new bulb in back in Feb. A new bulb should last at least one year running 12 hours per day, and typically longer for sets that are not on that much. The warning is triggered when the bulb's "on" time approaches 10,000 hours. Some bulbs last longer than 10,000 hours, but most should be replaced around 7000 hrs for optimum color and brightness.

The lumens for the 250 watt hps,mh ,are the standard amounts ! So , 27,500 lumens for the hps , and 18,000 for mh! the lights last around 24,00 hours, some bulbs are bad and will burn out in a month , this does happen :)
