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.
Incandescents produce 10 lumens per watt, halogens about 13 lumens per watt, fluorescents and LEDs 40-50 lumens per watt. Lumens measure the brightness, watts measure the speed at which electrical energy is used.
No. Only replace lamps in a fixture that the manufacturer of the fixture recommends. By installing larger than recommended lamps this could create a fire due to the increase of heat generated by the over size lamp.
There is no direct cross over replacement for the halogen bulb. The pin configurations are different. The halogen bulb has pins whereas the LED lamp is an intermediate screw in base. The LED bulb uses an intermediate base so that it can be screwed into a regular household fixture as a direct replacement for the old incandescent type bulb.
A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts. A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts. A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
Yes. It just won't be as bright.
The average lifespan of a 60 watt halogen bulb is around 2,000 to 4,000 hours.
Halogen bulbs are about 30% more efficient so a 70 watt halogen does the job.
A halogen bulb IS ITSELF a type of incandescent illumination source. A 40 Watt traditional incandescent bulb usually emits about 400 to 500 lumens while a halogen may emit close to twice that. So a 25 W halogen might give out as much light as ah older style 40 W 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.
No, it will not be. You will need at least a 50 watt halogen for outdoor lighting.
Almost twice as much as 100 is almost twice 60.
A 0 Watt bulb does not consume electric power so the cost is zero.
Strictly the power in watts measures how much energy is used, while the brightness is measured in lumens. Bulb packaging should carry that information. But 'equivalents' are a useful way for manufacturers to bamboozle customers, so halogens often carry an 'equivalent wattage' figure, which means the power of an ordinary old incandescent bulb of the same brightness. If you had a 100 watt old-fashioned bulb, that is replaced by a 70 watt halogen. It could also be replace by a 20 watt CFL bulb that is obviously less expensive to run and lasts much longer.
Incandescents produce 10 lumens per watt, halogens about 13 lumens per watt, fluorescents and LEDs 40-50 lumens per watt. Lumens measure the brightness, watts measure the speed at which electrical energy is used.
ahm...depends on the cost per watt charged by your local provider... how much is it?
