what is the rated life of these bulbs?

I looked in the tubes themselves and the documentation the manufacturer sent with them but unfortunately I don't see the rated life anywhere.

Sorry for the late response - Not sure about warranty but bulb is suppose to last for up to 30,000 hours. So far they are working very well.

These bulbs are rated for 8000 hours. About 1 year of you leave them on 24/7. I wouldn't recommend them for daily use, though; the ballasts seem to be VERY fragile - we've had a number of them, (the ballasts) just burn out after less than 10 hours of use. Other than that, I love 'em.

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

I have not had to replace any bulbs. It is my understanding that they last for many, many ours.

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

I am not sure how long they last as I installed them to use as reverse lights to shine on my trailer hitch and they work great. The bulb can't be replaced and if it ever blows you will have to replace whole light.

I cannot tell you anything about replacement because I have installed eight of these same GU10 replacementsand never received any bad bulbs. As for life span, I have not had any failures in 1 year of usage.

In my experience they last as long as other bulbs typically last. Mine were still working great and strong when we sold my truck.... it hadn't been years since the install but there was no sign of them going out anytime soon. (I think it had been 1-2 years since the bulb swap out from factor bulbs)

I don't know the rating but I have been using them in a semi covered fixture outside for close to a year with no problems.

One bulb lasted 2 years and the other about 2.5. The OEM bulbs I have back in have lasted about 13 years and are still going. They are not nearly as bright.

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.

thats a question for the manufacturer, but the led bulbs are normally rated for 7 years before any degrading begins.

Yes...I would echo what Rob said. I've been amazed at their longevity. I have them on a timer running about 5 hours EVERY night for the past two years. Only a few bulbs burned out...the other ones are losing their blue color finish due to exposure to sun/rain. Great bulbs.

I've had mine about six months so far, and they are still working great. I am very happy with these bulbs.

I've had these for a few month now, and so far so good. One I keep on downstairs on the first floor all night every night, and it is working fine. I could not comment on anything longer term. Hope this helps. Perhaps the other reviewers got bulbs from a defective batch or something...
