There are many different H3 bulbs that can be used, from a quick Google search, ranging in price from a few dollars (the actual bulb) to 15-20. One I found was stating 1550 lumens. My guess is they are not all created equal - more expensive ones may be brighter, or last longer, or a combination of the two (but not necessarily).
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
Well, if they're both 40 watt bulbs they use the same amount of electricity. But incandescent bulbs produce a lot of heat as well as light. Fluorescent bulbs don't produce (much) heat, so they can use their power to produce light. So you can use fluorescent bulbs of lower wattage to produce the same amount of light.So for the same amount of light, fluorescent bulbs use less electricity than incandescent bulbs.
The energy consumption of a modern Cree XP-G or XM-L based flashlight with 170 lumen output can be as low as 1.4 watts with 120 and more lumen per watt. The light output will be approximately equal to a 20 W tungsten incandescent light bulb or a 10 W halogen light.
It can only power a flash light!
no , it will burn out
Yes. It just won't be as bright.
A halogen floor lamp with a 300 watt halogen bulb will illuminate a room from wall to wall. While a halogen bulb gives off very radiant, bright light, you must be very careful because it also gets tremendously hot.
Halogen bulbs are about 30% more efficient so a 70 watt halogen does the job.
It's a halogen bulb
Approximately 15 lumens per watt for halogen, so 300 lumens.
Yes, the halogen bulb would provide about 30% more brightness (lumens) for the same electric power rating. So 70 watt halogen is about equal to 90-100 watt incandescent.
Lumens measures how bright it is, watts measures how much electric power it uses up. An old-type incandescent bulb produces about 10 lumens per watt. A halogen produce about 13 lumens per watt. A fluorescent (energy saving) bulb produces about 50 lumens per watt. LEDs produce somewhere around the same as a fluorescent.
No, it will not be. You will need at least a 50 watt halogen for outdoor lighting.

The rhyming word for a 100-watt bulb is "dull."
