300 watts is the correct answer
Halogen gas is in a Tungsten-Halogen Light Bulb.
Halogen H4 55 Watts 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.
PROVIDED * that the power of a halogen light bulb is not more than the maximum power rating of its lamp holder or light fitting AND * that lamp holder or light fitting is of a type suitable for its location and application to provide light, it should not be dangerous to leave a halogen light bulb "on" for several hours. In other words if a light fitting is rated at 150 Watts maximum the rated power of the halogen bulb used in that fitting must never exceed 150 Watts. As for any light bulb, if it were too powerful for its lamp holder or light fitting, there would be a serious risk of overheating. In other words, if a light fitting is rated at 100 Watts maximum and a halogen bulb rated at 150 Watts is used in it, there will be a serious risk of overheating which would lead to: * premature bulb failure as the least consequence and * catching on fire - leading to a house fire - as the worst consequence. As for any light bulb within any overall long period of time, if it were left on for a greater rather than a lesser percentage of that time, there would be two key consequences: * it would reach its rated service lifetime more quickly and would therefore have to be replaced more often during that overall long period of time; * it would consume more electricity and would therefore cost more money to run during that overall long period of time.
The heat dissipation is what the fixture is rated for. They are saying maximum heat of 25 watts so 40 watts is going to be too much.

Halogen H4 55 Watts bulb.
Halogens are about 30% more efficient so 300 watts incandescent is equivalent to about 210 watts halogen. It's also equivalent in brightness to about 60 watts CFL.
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.

The typical household light bulb is the incandescent, they come in a variety of watts. Most used is the 40 watts, 60 watts, and 100 watts. Incandenscent are inexpensive and are the most common bulb for traidtional homes. Although fluorescent light bulbs are common in kitchens. Halogen light bulbs are more effeicient than incandecent they are better suited for offices, kitchens and lmaps. CFL (Compact Fluroescent Light) Bulb last longer than traditional incandescent. The LED (light emitting diodes) are becoming popular.
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.

Can I use 50 watts light bulb for weed plant
a light bulb is measured in watts
The heat dissipation is what the fixture is rated for. They are saying maximum heat of 25 watts so 40 watts is going to be too much.
Halogen light bulbs are made in a variety of sizes to meet different needs.
