Not enough information is provided by the question, however, it is simple enough to determine the wattage required for the projector with a multimeter. Measure the voltage (120V likely in the US) and current with the multimeter. Then multiply them. For example, if you measure 120 volts and 5 amps, then 120V x 5A = 600 watts. Another device you can find on Amazon is the "KILL A WATT" that your can plug the projector into and it will directly measure the watts or volt-amps of the projector. Now it gets a bit more complicated. If the lamp in the projector is a "high intensity discharge" type lamp (Mercury vapor, for example), then the UPS you want must be "fast transfer" so the projector (and lamp) doesn't lose power for any appreciable amount of time. The "fast transfer" UPS's are significantly more expensive than the simple backup battery packs that Amazon sells for less than $100. That type will work with a lamp that is an incandescent type. This answer was provided by an electrical engineer who works in the power systems field.
There are 5 ampere hours in 5000 mAh
9260 km are there in 5000 nautical miles.
A 30-watt fluorescent tube typically produces between 2,400 to 3,000 lumens, depending on the specific type and efficiency of the bulb. Generally, standard fluorescent tubes have an efficacy of about 80 to 100 lumens per watt. This means that a 30-watt tube can provide substantial illumination for various lighting applications.
The mass is 5000 milligrams.

A good projector will have 2000 or more lumens, but an LED projector will have much less.
Da-Lite, the projector screen company has a great calculator here and even includes a brand and model reference.
The number of lumens required from a solar panel is not directly correlated to its wattage. A 100-watt solar panel typically produces around 300 to 600 lumens per watt, depending on the type of lighting used. Therefore, for a standard 100-watt solar panel, it can produce about 30,000 to 60,000 lumens when fully utilized, assuming it is connected to LED lights or similar efficient lighting systems.
700 lumens
100 lumens=1257 candlepower from what I have found
Approximately 15 lumens per watt for halogen, so 300 lumens.
2300lm Comment I think you mean lumens, not lumen's. No that answer is wrong Watts (energy usage) / Lumens (light output) 25 is equal to 200 35 is equal to 325 40 is equal to 450 60 is equal to 800 75 is equal to 1100 100 is equal to 1600 125 is equal to 2000 150 is equal to 2600 36 watts would be about 350 Lumens
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.

A 1141 bulb typically produces around 185 lumens.
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.
Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.
