How many hours of desk lamp use at the *brightest* level of brightness?

I have not timed it so cannot give an exact time. If the unit is fully charged, the average use time is approximately 7 hours. Thanks for the question! Don Carter, CEO, DTC LifeTools

Dear friends,ZITRADES Trademark Desk lamp is not normally desk light. it's one Idea desk lamp. long time reading as below: 1 touch with strong light can use 1-1.5h. 2 tourch with middle light can use 4-5h. for the 3 touch can use 8-9 hours. no worries for that ,you can go and buy them from ZITRADES directly. thank you ZITRADES

From my (manufactured Jan 2014) LFP S300 on High, a CONSTANT "specified 85 Lumens" for 6.5 hours. A 13 hour runtime for Medium. At 59% of maximum output, a constant 50 Lumens. A 26 hour runtime for the Low setting, with a constant 25 lumens. The 3 lumen Nightlight setting ran [continuously] for over 174 hours.

Its bright enough to read by, I'm not sure of the # of lumens, it gave off enough light for the room. I had it going for approximately 2 hrs on a full charge when I shut it off, so I cannot tell you how long it would run.

divide 6000.hrs by 24.hrs equal 250 days / so unless you run unit for 24.hrs for 250 days/ lamp should last at least a year .(good bet ! )

I would say they are pretty accurate. Doing normal web browsing at 50% brightness could run 8 to 10 hours.

I typically use the head lamp for 30-45 minutes at a time on high power and will get about 10 hours of run time before noticing a drop off in the light level.

Actually, it depends on what you mean by "Maximum brightness" as the P12 starts off at 950 Lumins (aprox) in the highest mode, but then starts lowering the light output after about 3 minutes in order to protect the lamp from overheating. It will keep lowering the output until somewere around 400 lumins were it will continue to run the manufacturer advertised 60 minutes for CR123's/1h 15m for a rechargeable 18650. My first use showed closer to 40min on CR123s of questionable quality.

Certainly, just lower the brightness if you are planning to spend many hours on spreadsheets, etc.

The time greatly depends on the brightness of the screen. At a moderate intensity, I'd say 4 - 5 hours.

I have the lamp on one end of a work table that is 4 feet long and 16 inched deep. At full bright, the lamp illuminates the entire surface, but is brighter at or near the lamp. If it were elevated above the surface in the middle back of your desk, it should provide decent work light on most of the surface. This is LED light, not incandesant, so at the same brightness it has a softer bluish appearance. I hope this helps your decision.

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

Yes. There are three levels of brightness. The brightest one is almost too much. I use level 2.

My best guess is 4 to 6 weeks. A lot depends on frequency and brightness which for me is important.

I'm not sure how long it may last but it depends on the settings of your pc. Example your brightness and power management!

I'm not sure, except that I wanted the brightness. I work on a lot of electronics with tiny parts, and this lamp works perfecyly for me.

I think the answer is somewhere in the reviews and my guess is at least a hundred. I use it in my bedroom to work in bed and it is plenty bright for that. If I look directly into it I am blinded for a few moments. Unless you want to light an entire room, this light should be bright enough for reading, crafting, computering, etc.
