Will four 50 watt halogen bulbs give as much light as eight 40-watt incandescent bulbs?

If the fixture was the exact same, and one held a single bulb and one held a double bulb
then NO. The light given off bulbs is marked as wattage when you look at the package.
So a 100w bulb has less light than two 75w bulbs together, because the two
equal 150w.

∙ 9y agoA halogen bulb gives about 25% more light than an incandescent bulb of the same power in watts. So eight 40W incandescents can be replaced by six 40W halogens.
CFL bulbs produce 5 times more light for the same power, therefore eight 40W incandescents can also be replaced by two 40W CFLs.

∙ 10y agoNo, halogens produce only about 30% more light than incandescents, so a 35 watt halogen is equivalent brightness to a 45 watt incandescent.

How much electricity needed for 100 watt compact fluorescent lamp?
The answer is simply100 Watts. The Wattage rating of electric light bulbs is just the amount of electricity they consume. So a 60 Watt bulb would take 60 Watts of electricity. In fact, if you could buy a 100 Watt CFL, it would have the light output equivalent to about eight 100 Watt conventional (incandescent) light bulbs.
When is a bulb better than a LED?
Never (Ithink!) Lumiette FPL bulb will be better than LED,i think The Xcellume PAR 38 FPL is said to reduce power consumption by 75 percent over the equivalent incandescent bulb, lasting four times longer than a typical CFL and eight times longer than a halogen lamp. The bulb will work with any existing medium screw-based socket in a residential environment, and is compatible with most dimmers.
Why will an alkali metal often combine with a halogen nonmetal to form a compound?
Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.
What element will have a noble gas configuration if it forms an ionic bond by accepting one electron from a sodium atom?
Every halogen has the capacity to accept one electron from a sodium atom and to thereby achieve a noble gas electron configuration of eight valance electrons. The halogens are fluorine, chlorine, bromine, iodine, and astatine.
How are valence electrons calculated?
You can look at the periodic table of the elements and determine the number of valence electrons in that element. The Alkali metals have one The Alkaline earth metals have two The Transition metals have one to three, it depends The Boron family have three The Carbon family have four The Nitrogen family have five The Oxygen family have six The Halogen family have seven The Noble gases have eight
What is the hottest light bulb?
There are two main types of commercially available energy-efficient light bulbs. These are LEDs and CFLs. Both are better than traditional incandescent light bulbs when it comes to energy efficiencyThe efficiency of light bulbs is calculated by comparing the amount of light produced to the amount of energy consumed:LED bulbs produce 90 to 112 lumens per watt.Compact fluorescent lamps or CFLs produce 40 to 70 lumens per watt.Traditional incandescent bulb fixtures only produce 10 to 17 lumens per watt.There are other considerations: Compact fluorescent light bulbs have a life span of eight to 10 years and cost about $4 per bulb.LED bulbs last up to 40 or 50 years but can cost over $306 per bulb.CFLs contain mercury which may require special handling for disposal while LEDs do not.

How many valence electrons do the halogen have?
The number of electrons in the valence shell of a halogen is 7. What is probably the most significant feature of halogens is that they all are one electron short of the number of electrons required to fill their valence shells, eight. That means they will have similar chemical properties, i.e., they all are on the lookout to borrow one electron.
Is it safe to swap eight numbers of 400 Watt Halogens with 16 100 watt CFLs?
Where in the world are you finding 100 watt CFLs? 32-35 watts is about where those things top out, which is a pretty bright light, the equivalent of about 150 watts incandescent. Or -- perhaps you mean 23 watt CFLs or something, which have about a 100-watt equivalent when compared with incandescents. At least at the beginning of their life they do. So if that's the case then eight 400-watt halogens can be changed out with sixteen 23-watt fluorescents, which will end up at about half the brightness, and have a greenish / bluish tinge to the light over time. You may want to splurge and get 32 watt bulbs, which will look like roughly 150 watts of incandescent light. One of the really cool things about using CF is less heat in the summertime, so the A/C doesn't have to work as hard. what is what Wat is what misspelled.

The fuse is blown or the bulbs are burned out or the dash light dimmer switch is turned way down or off.

This atom become an anion with negative charge -1.
