BatteryStuff Tech A 50 watt light bulb will draw 4 amps at 12.5 volts DC (Watts = Amps x Volts). 3 bulbs will draw a total of 12 amps per hour. For 6 hours, that‘s 70 amps. For 3 days, that‘s 210 amps total draw. A 130 Amp Hour battery will not cut it, especially considering an 18 watt solar panel will only charge at a rate of 1.25 amps per ...
The Solar Panel Calculator below is designed to help you establish what sort of solar panel kit you'll need to power your appliances. Once you have thought about what appliances you want to power using solar energy, check the user manual or the appliance itself to establish the wattage.
The final part to sizing your solar system is the solar panels. The power generation rating of a Solar panel is also given in Watts (e.g. our part number STP010, is a 10W solar panel). In Theory, to calculate the energy it can supply to the battery, you multiply Watts (of the solar panel) by the hours exposed to sunshine.
Lumens are the new unit of measurement for light bulbs. For decades, we’ve been buying light bulbs according to wattage. But as energy efficient, low-watt light bulbs like CFLs and LEDs have become readily available, watts have become an unreliable metric for selecting bulbs.
More Watts doesn’t always mean a brighter light bulb. To choose a light bulb with the right brightness, think lumens, not Watts. In the past, if you wanted a brighter bulb you’d simply choose one with more Watts. For example, most 75 W bulbs – irrespective of brand – put out about the same amount light.
New higher efficiency standards for light bulbs were put into law through the Energy Independence and Security Act of 2007 (EISA) and became effective nationwide January 1, 2012. Most bulbs are required to be 25% more efficient by using less energy in watts to produce the same amount of light, measured in lumens.
The worksheet will calculate your total Energy Storage (Wh/day) and Peak Power Rating (Watts). Use the Storage (Wh) and Power Rating (Watts) to select the right solar generator for your home backup, outdoor/RV or portable charging requirement.
A typical single LED light will give off the equivalent of a 2 watt bulb. As a comparison, an average 100 W incandescent bulb produces about 1,700 lumens, or about 17 lumens per watt, whereas LED lights produce anywhere from 65 - 90 lumens per watt. This equates to LED lights being about five times more efficient in their energy usage.
The calculator will work with any type of existing or replacement bulb. Simply enter the requested information and watch the values change (remember to hit 'return' or 'enter' on your keyboard after entering or changing a value). If you are changing the bulbs yourself, leave the "Re-lamp labor cost" field at zero.
Designed for bathroom vanities or anywhere a globe bulb is required, these bulbs produce light equivalent to a 40-watt incandescent bulb, yet only consume 10 watts of power. Dimmable from 100% to 10%, these bulbs have a 200 degree beam angle to cast light in a wide area.
Generally, path lighting is considered decorative accent lighting. But it’s actually very useful for visitors to see the walkway. Solar LED path lighting has come a long way.Bollard lights are a popular choice for effective path lighting. 100 lumens is considered bright enough for most walkways — including commercial properties. 100 lumens is equivalent to about 20 watts.
The light bulb lumens chart / wattage chart below will help you understand which CFL or LED bulb is comparable to your current incandescent bulb. Simply take your current incandescent watts and select the corresponding CFL or LED bulb equivalent on the lumens brightness scale.
Using the chart we can see that if you want to replace a 40W incandescent light bulb with a compact fluorescent (CFL), you will likely need a 7W CFL. Similarly, if you want to replace your 53W halogen light bulb with a modern LED, the LED will probably use between 9 and 13 Watts of energy.
In this video we show how you can save money by replacing your cheap incandescent light bulbs with more expensive LED light bulbs. We use the Kill-a-Watt power meter to measure actual power ...

The power result in watts will be displayed as; = 83.333333333 watts (W). This calculator uses a particular formula in executing the conversions. Formula of calculating Lumens to watts P (W) = Фv (lm) / η (lm/W), which means that the power in watts is calculated by dividing the luminous flux in lumens by the luminous efficacy in lumens per watt.
Typical household lighting. 1. Think lumens, not watts. We used to purchase old fashioned incandescent bulbs by the amount of power (or watts) they used. With the energy-efficient new technologies now available light bulbs now produce the same amount of light using far less power. It no longer makes sense to shop for watts.
For example, a correct replacement for a 60w incandescent bulb would be a 15 watt CFL bulb (60 * 1/4 = 15). While the math for the CFL bulbs is simple, the LED bulbs are even more energy-efficient and durable than compact fluorescent light bulbs. LEDs require less wattage than CFL for the same amount of light.

The voltage V in volts (V) is equal to the square root of the power P in watts (W) times the resistance R in ohms (Ω): Watts calculation. The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): The power P in watts (W) is equal to the squared voltage V in volts (V) divided by the resistance R in ohms (Ω):

The incandescent bulbs, which our LED's replace, quickly degrade by 60% to the "Designed Lumen Output" listed on the chart. Thus, within just a few hours of use, many of these incandescent bulbs are less bright than our LED bulbs, but they still require 90% more amperage to run. Also, LED bulbs last 40,000-60,000 hours.
Lightbulbs: Watt-to-lumen conversion chart . Advertisement. We all know how much light a 60-watt bulb will produce. But the brightness of new CFL and LED lightbulbs are measured in lumens, not watts, so here’s a handy chart to help you do the conversion. Lightbulb Watt-to-Lumen Conversion Guide.
