The size of this light is similar to or slightly bigger than a typical LED light bulb that you normally use at a table lamp, it would still fits a table lamp without any problems. This light can be used a regular LED light bulb and be mounted in a lamp socket for daily use. One amazing aspect of this bulb is that it keeps on even when there is a power outage, as long as you flip on the light switch, and it will stay on for a few hours, which is very neat. During camping or outdoor events, this light comes very handy, you can take this bulb, either with the cap or without the cap (it is better with the cap, from my experience). When you put on the cap, there is a button which you can push to turn on the bulb, or, if you do not have a bulb, you can use your fingers to touch the two ends of the bulb base simultaneously and the bulb will turn on--it uses the conductivity of the human body--which is cool and would be a nice trick for the kids. A major advantage for this bulb over the light torch for emergency lighting is that this bulb gives you a wide range of lighting, which provides more safety, so it is kind of a moving lamp, but much portable and more light-weight, also it is safe and versatile, which makes it a very cool thing to have. The key thing is: the light bulb needs to be in a closed circuit in order to be on. For example, when you put it in a regular lamp socket and turn on the switch, it will turn on (even when there is a power outage it will keep on for hours), so even if you cut the power, as long as the light switch is at the "ON" status, the light will be on. Or, if you hold the metal base with your fingers, it will also turn on (when the battery is not drained), because in this case your body sort of creates a closed circuit for it as human body can conduct electricity. But if you put it in the lamp socket and turn off the switch (whether there is electricity or not), it won't be turned on, why? Because it is no longer in the closed circuit status. Just be aware of that so you know what you will anticipate when you use it.
