How many hours is this bulb rated for?
929381
who cares how long they are rated when they are so cheap? And have you ever believed the ratings anyway?They are bright enough to read by, and less warm than I prefer. It is like a "daylight" bulb.

Don't know how long it is rated for, just know that it is working in a field station in the Amazon (the river basin) where it is subjected to very high heat and humidity, so I think those will be the factors that limit its life.

I'm not sure about the hours but the bulb produces amazingly bright light for a bulb of this wattage.

I don't use the bulbs that much, But I have some over several years......... They do last a long time....... but I'm not able to get you an hour count...........

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...

It is supposed to last 5000 hours. Considering it's a $10 light bulb, I doubt there is a replacement warranty.

Hi Ronnie, the lifespan of this bulb is estimated at 50,000 hours. This includes lumen depreciation and other factors. Most high quality LED bulbs are rated by Energy Star at 30,000 to 35,000. Thanks!

LED bulbs are typically soldered in place instead of socketed with a typical lifetime of about 100,000 hours. That translates to 20-years worth of night time only service. It is the rare LED bulb that would fail much sooner than that. I deal with them in all kinds of ways as a broadcast engineer.

The specified lifetime I believe is 10,000 hours under normal usage. I'm not sure if "Base Up" is considered normal usage. I say this because the electronics are in the base, heat rises, and this may degrade the normal lifetime of the bulb. Be sure there is plenty of airflow around the base and the bulb.

According to UCI (I called them). It will shine/burn for 2 hours @150 Lumens, then it will start to dim and go into power saving mode.

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

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.

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".

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.

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.

The info on the bulbs (6) I received with my growing system say "SunBlaster F54T5 54W HO 6400K". I found them and similar ones on the internet. I believe they are rated for 10000 hours. So far (after 2 months use) mine are working great!

It's based on 3/hrs of day of use, which is 1,095 hours/year, or about 22.83 years. As with any product, using it more or less frequently will extend/reduce the life. In my own case, I've used three of these for more than 3 hours a day for 2.5 years or so, and have not had any issues so far. Also, the lifetime quoted assumes you follow the directions (i.e., don't install this in a *fully* enclosed fixture as the heat buildup will rapidly degrade the LED).

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.

Mine have lasted over 2 years thus far, 24/7 usage and I have two units. I highly reCommend this, you aren't going to find a bulb that will last half as long, either way. It's a piece of mind.
