We love our LED lamps (See Five Best Energy Efficient LED Desk Lamps) for energy efficiency, low heat production and for the size of the light bulbs. What we don't love however, is the price (with most costing more than $99). See a couple ideas on making your own after the jump.
LED Panel Light:
Instructables user KresimirPregernik took it upon himself to rebuild an old halogen 12W lamp into a modern LED Panel light, pictured below. Using Plexiglas was used for the panel, drilled for LED foots, and the LED's were also painted with an alcoholic silver paint pen to increase light in the front direction.
LED Hardrive Desk Lamp
The LED Hard drive desk lamp (Pictured above in the top photo) by Instructables user mikedoth turns an old hard drive into a functional LED light. 12 LED's from an old set of Christmas lights were used and the whole unit is powered by an old cell phone charger.
LED Floor Lamp:
Instructables user Torrach turned a halogen floor lamp into a safer, more efficient LED Floor lamp that even uses recycled materials. The steps are involved, so visit Instructables for the how-to.
