prompter: What is the typical wattage of bulb in a lightbox?

assistant: The typical wattage of a bulb in a lightbox is 60 watts, although domestic LED bulbs are normally much lower than 60 watts, as they produce the same or greater lumens for less wattage than alternatives. A 60-watt Equivalent LED bulb can be calculated using the 7:1 ratio, which divides 60 watts by 7 to get roughly 9 watts.

prompter: Rewrite your description of the typical wattage of a bulb in a lightbox to only include the key points in a list format.

assistant: The amount of electricity that a light bulb uses depends on its size and type. Traditional incandescent bulbs usually consume between 25 to 100 watts, while LED bulbs use between 2 to 18 watts. Most light bulbs draw around 110 volts and less than 1 amp.

However, the biggest factor that affects the amount of electricity a light bulb uses is how often it is used. In the United States, the average time that lights are on per day is about 2 hours. For example, using an average 60 watt incandescent bulb:

Using the light bulb for 1 hour per day results in 0.42 kilowatt-hours (kWh) of electricity per week, 1.83 kWh per month, and 21.9 kWh per year.
Using the light bulb for 2 hours per day results in 0.84 kWh per week, 3.65 kWh per month, and 43.8 kWh per year.
On the other hand, using the light bulb for 3 hours per day results in 1.26 kWh of electricity per week, 5.48 kWh per month, and 65.7 kWh per year.

An LED light bulb, which is more energy-efficient and averages around 10 watts, uses less electricity than a traditional incandescent bulb. 
For instance, using an LED bulb for one hour per day results in 0.07 kilowatt-hours of electricity per week, 0.30 kWh per month, and 3.65 kWh per year. 
Using an LED bulb for two hours per day uses 0.14 kWh per week, 0.61 kWh per month, and 7.30 kWh per year, while using an LED bulb for three hours per day uses 0.21 kWh per week, 0.92 kWh per month, and 11.0 kWh per year. 

Keep in mind that you usually use more than one light bulb when turning on the lights, so the actual energy usage may be higher. By multiplying the numbers above by the number of light bulbs used in a room or throughout a house, you can get a more realistic estimate of energy usage.

prompter: How much power does a fluorescent lightbulb typically use?

assistant: Fluorescent light bulbs usually consume between 8 to 100 watts depending on their size and type. Compact fluorescent bulbs, which are the most common type, typically use between 13 to 23 watts, while larger fluorescent tubes may use up to 100 watts or more. Like other types of light bulbs, the actual electricity usage will depend on how often the bulb is used.

assistant: For photography, continuous lights are available in multiple forms, like tungsten lightbulbs, fluorescent lamps, and LEDs. The power of individual lights in the array will vary based on the lighting technology (tungsten, fluorescent, or LED). LEDs tend to be more energy efficient, and individual lights in a light box commonly range from less than a watt to four watts.

prompter: How many lightboxes can I plug into a single outlet source?

assistant: The number of lightboxes you can plug into a single outlet source will depend on the wattage of the lightboxes and the capacity of the outlet. As a general rule, it's recommended not to exceed 80% of the maximum capacity of an outlet. So, if you have a 15-amp outlet, for example, you should avoid plugging in more than 12 amps of lighting equipment. You should also make sure to use surge protectors or power strips that are designed to handle the load of your equipment to avoid damage to the devices or the electrical system.

assistant: The number of lightboxes you can plug into a single outlet source depends on the circuit's capacity, which is measured in amps and watts. The National Electric Code prescribes that the maximum cord-and-plug load connected to a receptacle in a branch circuit that supplies two or more receptacles should be 12 amps for a 15-amp outlet and 16 amps for a 20-amp outlet. As a rule of thumb, it's safest to stick to a maximum load of 1,500 watts per outlet or circuit. However, it's essential to calculate the total combined wattage per outlet by checking the label or manufacturer's instructions for each device or appliance to avoid overloading. It's best not to use more than two appliances in a single outlet to prevent fire hazards.

prompter: Provide a few lightbox product recommendations as I am currently interested in buying one for art.

assistant: Warning...
You need to know the correct Amperage of your system and how much it can handle, check your appliances for their usage, leave 20% headroom in Watts.
