I have a friend living in St. Thomas, USVI. Due to Hurricane Irma, he will be with out electrical power for many more months. I purchased 3 d.light s 300 solar lanterns, and three d.light A1 Led lights. It was extremely costly to have these items delivered to ST Thomas. Only 2 of the 3 S300 model worked. The number on the carton for the item that didnt work is X000F979QZ. Given the situation, there is no way to return the item. This is very disappointing.

After reading the positive reviews of this product I decided to purchase it because it is perfect for emergency purposes such as blackouts. Where I live these happen several times per year. I haven't had to use it yet but I like the fact that no batteries need to be replaced and you can charge your cell phone. I also like the fact that it can be charged through usb port and solar panel. I tested both and they work great. The lantern itself is sturdy and easy to carry. I would recommend this product to my friends and family. Good product

Awesome awesome awesome !!! I ended up buying FIVE of these, I keep meaning to gift some but can't bear to part with them :) Don't hesitate to buy this light! I have a lot of solar lights (we live in the mountains with power outages in the winter) and this is my absolute favorite. It comes with a long cord so you can put the charger where you need it. It will charge in cloudy weather but takes longer. I think it takes about an hour for a full charge on a sunny day. I like to use it at night to read by and turn off my bedside light, nicer light and saves energy. Also let's me enjoy my candles at night. The advantage of having at least two is that when the charge goes out on one you can use the 2nd one until you charge them later. No dark nights. I get about a week from one charge.

Reviewed in the United States on May 27, 2015
This light has been a huge disappointment. I originally bought one for a Christmas gift, but it didn't charge - at all - despite leaving the solar panel in bright sunlight for days at a time. So I returned it for a replacement, which seemed to work at first. At least it would charge enough to turn on, which at the time is all I checked. Took it on our first camping trip this month, left the solar panel out in the sun all day (maybe 5-6 hours), and it turned on. Hooray! For about 10 minutes, then it died completely. Boo!

So yes, it does charge, and it is mighty bright when it does work. (Which is why it's getting 2 stars instead of 1 star. And the multiple settings option is nifty.) But it takes an inordinately long time to charge, and didn't last very long when it did. I would return this one too, except that I've had it too long. We'll keep it to use in a pinch, but it's not something I'll depend on to use on camping trips, or regularly at all for that matter.

I was also disappointed that it doesn't come with any instructions or helpful tips. No paperwork at all, in fact, not even instructions on the box. It would be more helpful if the manufacturer gave you some idea of how long it takes to fully charge, what the indicator light thingy is actually telling you (when it's flashing that means it's charging, I guess? Maybe??), and how long you should expect it to last based on how long it's charged for. Just any info at all would be helpful. Even returning the first one was difficult, because despite the fact that it's got a 2 year warranty the manufacturer won't take it back but insists you return it to the Point of Purchase, and Amazon will only take returns within a specified time period. But it took me a while and a bit of web sleuthing to figure all that out, because there is no paperwork!

Anyway, I hate writing negative reviews, but this particular product could use some serious improvement, and this manufacturer could use some better customer service practices as well.

Reviewed in the United States on October 12, 2014
This new model compares favorably with my previous [Feb 2011] S250 - which I earlier resurrected by extended trickle charging (courtesy of N.Lee-theEngineer); after I had left it unused for so long (over a year?) that the NiMH battery pack had dropped below minimum charging voltage.

Full USB charging takes just over 6 hours - a little surprising as I had the impression that the new battery [pack] may have been LiFePO4, which offers more efficient charging?
Perhaps this lengthy charge period is for consistency with PV charging - requiring a FULL sunny day.

My High output cut out after 6h 29m; with Medium lasting just on twice this at 12h 56m.

So a 30% improvement from the 5 hours on High I got from my old S250 - 3AA NiMH 1.5Ah battery pack.
It is possible that this new S300 lantern uses 2Ah NiMH cells (although the lantern is ~9g lighter)? If so perhaps these are Low Self Discharge batteries like the "gold standard" eneloops. Which also offer some 2,000 full cycles - similar to the robust LiFePO4 cells. Unfortunately I can't unscrew this later lantern to see - as I did with my S250.

In any case 2,000 full cycles gives over 5 years on a daily cycle.
In that time LED efficiency may well have doubled - with battery technology improving too.

As we third chimps see in an exponential fashion, a doubling of runtime means that apparent brightness is ~70% (the Inverse square law). With a quadrupling of runtime leaving us with half a perceived full brightness.
A 25-fold increase in runtime [resulting in a 25-fold reduction in full illumination - ie lumens]; would suggest a 'seen' 1/5 of 'High' illumination for the Bedlight setting ... (1/25)^0.5

EDIT: D.light were kind enough to confirm that they now do use the extremely long life LiFePO4 (LFP) batteries
http://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery
which in my experience [at least initially] improve given run times by some 60%.

My latest test at the [16 hour] Low setting cutting out after 26 hours & 3 minutes.

Out of interest I also fully charged my basic Nokia phone which was initially showing just 50-75% full!
The partially battery depleted S300 is currently on at the Bedlight setting. It is probably academic whether this lasts some 160 hours from a full charge ;-)
What I am interested in is whether a slower, lower, rate of discharge results in a deeper total discharge - requiring a [slightly] longer recharge. There is some suggestion that this may be the case.

What I do find impressive, however, is the consistency between experienced runtimes at H/M/L settings.
If lumens output are correspondingly halved, then quartered - this safe LFP battery, with its steady 3.2V output, would seem to offer a level of efficiency I have not previously seen [as an enthusiast] in multi-level Lithium battery flashlights - even very expensive ones.

FURTHER TESTING: I turned off the Bedlight setting after running it continuously for a full week - 24/7. Turning it on the following day the lamp finally cut out after a few hours. so over 174 hours on the Bedlight setting from a fully charged battery.

Although I purchased my S300 on Sep 10, 2014, the date of manufacture is given as Jan 2014.

Using a light meter I compared the output under each Mode, with the Runtime:

- Full output is specified at 85 Lumens; & I got a steady output (within 1% tolerance) from this new LFP battery for the full 6.5 hour runtime - although my checking didn't cover the last 5 minutes.

[Giving, what I might term 552 LumenHours from a full LFP battery.]

- With runtime doubled at 13 hours for an intermediate level of illumination, output reduced to 59% of maximum - implying a 50 Lumen output, for 650 LumenHours.
Of interest this shows the higher efficiency of an LED when under-driven!

[I checked the light levels (Lux) at all 4 Modes - both initially, & 5 hours into the 6.5 hour full-output run.]

- 25 Lumens being suggested for the Low 26 hour runtime.

- Just some 3 Lumens for the Bedlight setting.
Although a full runtime of over a week is not to be sneezed at ;-) I did wonder whether a less efficient method (perhaps PWM) had been used to reduce illumination to this very low level?

Of interest with using a mains (Oz 240V) Belkin USB transformer [having a 0.5W overhead], to recharge a fully depleted battery took under 7 hours, using just 16Wh!
So under 6kWh a year for 365 'full' recharges.

As a flashlight enthusiast I find this new LiFePO4 battery surprisingly good.

My testing was done in cool conditions (~68F) with a new S300.

I intend to duplicate my testing using a 'new' & different type of Lux Meter - with more significant figures for accuracy.
I don't anticipate any significant differences, but I will amend my review if any are encountered.

IMHO the steady [CONSTANT] output, & longevity of a LFP battery make this the 'standard' for rechargeables!!

5.0 out of 5 stars Multi-use and great value. I have bought multiples.
Reviewed in Canada on April 17, 2015
I have had one of these units for two years now and they are amazing. They are almost indestructible and very easy to use. The light is amazing and the 4 levels make it very adaptable to many situations such as in a tent hanging from the ceiling to a work light or a flashlight for walking or even reading for long periods. Use it in our tent and RV and for emergency lighting, in the car on the road and great for kids. The dongle to allow you to recharge small electronics is a bonus and great for cell phones and other devices. I bought two more for gifts I am so impressed and also bought the lantern.

Reviewed in the United Kingdom on October 28, 2014
Just finished a weekend away with my scouts. Brought the solar lamp instead of the usual Coleman Dual-fuel lantern. It performed excellently. Used for 6-8hrs both nights. Light from it is good for "floodlight" type use putting up large Icelandic type tents and for inside our leaders mess tent later in the night. It charged well for 8hrs on a day with mixed autumn weather so we could use it again the next night. It impressed my other leaders and the other scout groups who saw it charging on the roof of our mess tent. Its half the price of our previous traditional light sources. It has no consumable and fiddly mantles. Its safe to leave unattended and with young scouts. There's no obvious weak points to break unlike glass lanterns. I'll be looking to convince our Quarter Master to get more of these when replacing our existing lamps (which won't be long) and am recommending them for the "Tented Village" in our national campsite.

5.0 out of 5 stars Yet another great product from d.light.
Reviewed in the United Kingdom on December 30, 2015
Yet another great product from d.light. I have the s2 solar light and was so impressed with it I bought the s300. It is extremely well made and you feel confident that if you dropped it it would remain in one piece. The four light settings have a clear demarcation between illumination settings. The lowest is still bright enough to read by and give up to 100 hours of light at this setting. The highest setting is bright. Seriously bright as in it will illuminate a whole room if hung from the ceiling. The down side being illumination time is reduced to around 4 hours. However, if used for camping to illuminate a tent or awning you wouldn't need that level of brightness. The solar panel needs direct sunlight to charge and this is my only tiny criticism. The S2 unit will charge from indirect light but the battery and power required for the s300 is larger and I guess that's why it requires more intense light to charge. Having said this on a typical British summers day it will not be an issue. All in all a brilliant product and an absolute bargain at the current price of £35.
