Three features drew me to Onite’s USB LED, and each has pleased me thus far, so I’ve decided to buy more (instead of trying the competitor’s much costlier USB LED):
1. Fair price for a solid product: bulb, cord, switch, and USB plug seem to be well constructed; if time reveals something not presently apparent, I’ll be back.
2. Convenient, sturdy metal hanging *hook*: hangs the bulb without the fuss threading something through a hole.
3. Soft, warm-light ambience: yellow tones complement human beings and are more restful for the brain.

The cord and switch are conveniently proportioned, too. To help you anticipate whether the lengths will work for your purposes:
Top of switch to bulb = 23.6″ (60cm)
Bottom of switch to top of USB plug = 36.5″ (92cm)
Switch is approx. 2.4″ long (6cm)

I also appreciate the packaging: a sturdy plain box that’s reusable; careful padding inside; no excess; easy to open.

The bulb is working splendidly. I power it with small solar-/USB-charged battery packs (capacity ratings from 2,400 to 13,000 mAh). I solar-charge my battery packs, and the main reason I bought this bulb (and wish to buy more) is to use less grid power. The other reasons are to light some spaces in my 1920s home that are not wired with sockets or outlets; and to add some “overhead” lighting to the kinds lighting I have for power outages and off-grid wanderings.

If you also intend to power your bulb with a rechargeable battery pack and want guidance choosing 5V battery capacity (measured in mAh) or estimating how long you’ll be able to light the bulb with a battery pack you already own, here are some rough guidelines:
– For 3 hours of light, choose a battery source rated at least 2,400 mAh
– For 5 hours, at least 3,900 mAh
– For 8 hours, at least 6,200 mAh
– For 10 hours, at least 7,800 mAh

 

The above uses 620 mA (milliamps)for the bulb’s draw of current, because my bulb draws 0.62A (amps). Also, to be realistic and appropriately cautious, my calculations presume using 80 percent, not 100 percent, of stated battery capacity. (Why? Because it’s usually unhelpful to fully drain a battery; there are inefficiencies using battery power; some power pack mftrs rate their products’ capacities “generously”; over time, battery capacity declines; and recharging a battery the last few percentage points is slow and not efficient, especially if one is using another battery or a solar panel to do it.)

One caution, if you actually need “5 WATTS”: The Onite bulb I bought draws 0.62 Amperes at 5.04 Volts, which puts the bulb’s actual power at approximately 3.1 Watts (W = V x A).

The Technical Details erroneously states 5 Watts (note, btw, that the more expensive brand claims “2 Watts”). These are mellow ambient lights, and I experience the Onite as pleasing for its purpose. If you need intense illumination, or are trying to light a large space with one bulb/light, then you’ll need to explore a different kind of product.

With the wattage exception, the Onite product description and illustration are helpful (kudos). But the listed wattage clearly isn’t accurate (others have noticed this, too), so until the the product description is corrected, I delete one star and include this wattage note, since consumers deserve complete and accurate product descriptions on Amazon. (I have measured voltage and amperage with two reliable USB meters, both while powering the bulb with battery packs and while powering it from USB ports on my computer, which is plugged into a typical 110v AC outlet.)
