Halogen desk lamp has the advantage of being very compact and durable, but the disadvantage of consumer much (and therefore too hot). Had a halogen desk lamp 25W, so I decided to change the bulb by a set of LEDs that will light the same as the halogen.
The halogen desk lamp LED technology recently is starting to use for low power consumption and long life (up 100,000 hours; yes, one hundred thousand), which leads to fluorescent technology that is immediate, does not need heating or primer. On the other hand has the disadvantage of cost and consumption per candela (light unit) is slightly higher to fluorescent. For now it is only recommended for its price for flashlights and in areas where for security can not allow a bulb (eg caving) is founded.

Halogen desk lamp, I bought a flashlight of these that come into your head in a shop with Chinese goods for 10 euros, with enough power and LED’s to serve my purpose. Also had different intensities microprocessor controlled and powered by 4.5 volts: We have to replace the transformer 220 12V AC to AC by another that transform between 4.5V and 6V and is DC (direct current).
