9 volt alkaline batteries are not really meant for heavy discharge loads, and are not normally used to power lamps. The practical limit for any reasonable battery life would be about 0.5 watts. At this power level, you could expect athe battery to last only 2 to 3 hours for incandescent, and maybe up to 5 hours for an LED.

How Convert 9 volt to 230 volt?
Converting 9 volts to 230 volts would require a pretty hardcore step up transformer (Expensive) and you probably wouldn't have enough current to sustain the load.See discussion page for more information.
How much resistance does a light bulb create if it has a current of 25 mA around it in a 9 V circuit?
how much resistance does a light bulb creat if iyt has a current of 25 mA around it in a 9 V circuit?
What voltage is required to pass 0.5 A of current through a 4.5-W BULB?
To determine the voltage required to pass 0.5 A of current through a 4.5-W bulb, you can use the formula P = V * I, where P is power, V is voltage, and I is current. Given that power is 4.5 W and current is 0.5 A, you can rearrange the formula to solve for voltage: V = P / I. Plugging in the values, V = 4.5 W / 0.5 A, which equals 9 volts. Therefore, 9 volts is required to pass 0.5 A of current through a 4.5-W bulb.
What is the output voltage across the secondary of a center-tapped transformer rated at 9-0-9?
If measured on the two outside taps the output will be 18 volt. Measured from the center tap to either of the outside tap will give a reading of 9 volts.
What is difference between mAh and volt?
A milliamp-hour (mAh) is a measure of quality of a battery. It tells you how many hours the batter can provide one milliamp of current before it will die. A volt is the unit of electric potential. AA, AAA, C, and D batteries are all 1.5 Volts. A 9 Volt is 9 Volts. Car batteries are 12 Volts. AA's are typically rated in thousands of mAh. Cs and Ds are more, AAA and 9 Volts are typically less. If you know the power that a device consumes [i.e. Remote, wireless game controller], you can calculate how long your batters will last in the following manner. Time = [mAh / 1000] * [# of batteries * battery voltage] / device power Ex: Device is rated at 1W using 4 AA [1.5 Volt] batteries rated at 1000mAh. Time = [ 1000mAh / 1000 ] * [4 * 1.5 Volts] / 1 W = 6 Hours
Can you use a 13 watt CFL bulb in place of a 60watt incandescent bulb?
no because it would blow up because the socket would draw 13 watt not 9 watt
What is the brightness level of a 9 watt LED equivalent bulb compared to a traditional incandescent bulb?
The brightness level of a 9 watt LED equivalent bulb is similar to that of a traditional 60 watt incandescent bulb.
What size fluorescent bulb replaces a 60 watt incandescent bulb?
A 13-15 watt compact fluorescent bulb (CFL) or a 9-11 watt LED bulb is roughly equivalent to a 60 watt incandescent bulb in terms of light output.
What is the equivalent brightness of a 9 watts LED bulb in comparison to traditional incandescent bulbs?
A 9-watt LED bulb is equivalent in brightness to a 60-watt traditional incandescent bulb.
Can 2x 9 volt battery run a 60 watt globe?
No
What is the brightness level of a 9 watt equivalent LED light bulb?
The brightness level of a 9 watt equivalent LED light bulb is typically around 800 lumens.
What LED bulb same as 13 watt CFL?
A 13 watt CFL bulb is roughly equivalent to an 8 watt LED bulb in terms of light output. Look for an LED bulb with around 8-9 watts and a lumens (brightness) output of approximately 800-900 lm to match the brightness of a 13 watt CFL bulb.
Does a 9 volt battery light a light bulb?
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
What is the formula for finding out how many amps is required to achieve the full 100 watt output from a 9 volt bulb?
The formula is volts times amps equals watts, or watts divided by volts equals amps.
How bright is 400 lumens?
This is a bit less light than a 40W incandescent bulb (much less than a 9-watt CFL bulb, but twice as much as a 5-watt CFL mini-bulb).
How many amp hours does a 13 watt bulb use?
A 13W bulb consumes 13W/110V=0.118 A.If you use it for an hour, it consumes 0.118 Ah, for 2 hours 0.236 Ah, and so on..AnswerLamps don't use ampere hours, as this is simply a unit of measurement for electric charge. You probably mean 'watt hours' which is a measure of energy. A 13-W lamp will use 13 Wh for each hour it is used.
What is the battery life of a 9 volt battery on a 3.5 volt of a bulb?
The battery life (assuming it is a primary cell) is determined by the Ampere-hour drawn from it. You cannot connect a 3.5V bulb directly to a 9V battery. The bulb will fuse.
