help would b much appreciated
The easiest way to power a lightbulb with a solar panel is to keep everything at DC voltage. Get a 12V solar panel, a 12V battery, and a 12V lightbulb. I'm trying to put together an inexpensive solution below.
This LED bulb will plug into a regular light socket, just make sure you do NOT plug it into a wall outlet. AC will blow it up. It uses less than 2W at 12VDC. http://www.altestore.com/store/Lighting-Fans/LED-Lamps-Fixtures/DC-12V-or-24V-LED-Bulbs-and-Fixtures/LED-FLOOD-w-QTY-18-WHITE-LEDS-12-VDC/p4488/
This battery will power the lightbulb for about 20 hours. http://www.altestore.com/store/Deep-Cycle-Batteries/Batteries-Sealed-Agm/Universal-Ub1280-12V-8Ah20Hr-Sealed-Agm-Battery/p2003/
This solar panel will charge up the battery. Note that because the panel is a smaller wattage than the lightbulb, you will need to have it in the sun charging the battery longer than the time the lightbulb is running. For example, to create enough electricity to run the light for 2 hours, you may need to have the panel charge the battery for 4 hours. To charge it faster, you'd need a bigger, more expensive panel. http://www.altestore.com/store/Solar-Panels/1-to-50-Watt-Solar-Panels/Kyocera-12W-12V-Mini-Solar-Panel/p718/
