Hi, i have recently got into electronics and i need to build a very bright but portable LED light (This is to light up the inside of a cave for caving and climbing), companies like Inova there products are very expensive for what i want. I want this to be about 700 Lumens (looking at Luxeon LEDs) wide beam, cool white, last about 2-3 hours, all in a small case about 4 inches across 3 inches wide and 2.5 inches in depth and i need also to have a small switch that wont get turned off by accident and it will need to be recharged. This is just for handheld use. I'm thinking about using 2 Luxeon rebels @ 435 Lumens and housing them on a heat-sink in side this small case with a clear lid. Im not sure what stuff i need like drivers or what type of battery to use can any you help me or give suggestions?
Thanks, David
