RESULTS AND CONCLUSION The 70W light bulb produced the most heat. This light bulb has most watts. And it was the brightest because the shape is all connected. The only one that was not energy efficient. We would buy the 50W light bulb because it is in the middle of heat and brightness and it is energy efficient. The brightest bulb is the one with the highest temperature. MENU
