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 within24 hours, according to the site. PS...I Love mine!!

Depends on how much you use it, and what type of battery you use. The bulbs being used take very little amounts of juice from the batteries so you should get many hours from the batteries.

Warranty is 2 years for the unit but only 1 year for the bulb. Seems that the bulbs are the weak link for these products and this one lasts for about 4500 hours if you have set for max brightness but will last for about 10,000 hours if it's used on a milder setting. Here are the exact details: 10,000/6500/6000/4500 Hours (Education cycle/ECO+/Dynamic/Bright) 190W Overall I'm happy with my unit and haven't had any trouble.

Since this light uses an LED bulb you can expect 5 hours out of the 4 AA batteries it takes to power it. The bulb itself will give you 100,000 hours or about 10 years of use out of it just keep enough batteries on hand and you'll be fine

The light bulb is halogen and it is reported to have a life span of 4000 hrs. It is replaceable with a designated halogen light bulb from Phillips.

50,000 hours.... WELL WORTH IT as your plants will love it far beyond just a hid or t-5 etc (I would NOT use it alone unless your doing one plant...) And NO you can not change bulbs etc.. when its done its done... Its a TRADE OFF off being able to replace a bulb for BETTER growth! LEDS RULE YOU WILL never want to go back when you use it! I wont! I am already looking into a BIG ONE ie a REAL DEAL non ufo (PRICEY ONE) leds work that good!THAT GOOD...

Anywhere from 6-12 months of normal use. I believe they are rated for ~200 hours. These aren't "long life" bulbs. They're on the opposite end of the scale, "high performance".

I do not know. I try to have extra bulb on hand. During a power loss for about 4 days I used the light to read books. Sorry I am not in tune with total hours.

I dont know about the particular details, but I use it for a few hours so its not worth switching out a bulb for that time.

I do not see the estimated life anywhere in the advertising, I have had this bulb last as long as 4 years at an average of 12 hours per day.

Hi there. I got mine lamp last March and the bulb that came with it just burned out about 2 weeks ago. So a solid year for me and I've used it at least 8 hours a day, Monday-Friday in my home office, where I work full-time. Easy to change the bulb, too. The cover snaps right off and you just pop it out and plug in a replacement.

I would say they are long lasting, I have been using mine for a night light in my hallway, so it's on from 8 pm - 3 am every day - for the past 6 mos, and the bulb is still going strong.

Not much. I can't tell the difference and I leave it on all night. All bulbs still work

I'm sorry. I can not answer this question at this time. The lamp has not been used on an hourly basis . . yet.

No. It's an LED that's soldered to the wiring. But the LED should last around 10,000 hours, so replacing the bulb should not be an issue.
