I use solar when I can because I do some boondocking. To keep my 12v. use to a minimum, I have replaced all my incandescents with LEDs. There IS some heat with LEDs. A child can touch the bulb or fixture without being burnt though. My issue was electrical consumption and I chose what are called 'warm white' bulbs for ease on the eyes. M4products has been building his business for a while now and offers a very wide selection of LED bulbs. I was very impressed with his SERVICE. I have not had a bulb failure of any type for about 2 years so far. I have 3 40watt overhead fluorescents (now 16 watts each) I have converted and can run all 3 for about the amount of electricity it took to run one before the conversion. I can use any 12v. light as a night light. My wife often leaves her reading light on all night and she always follows me turning out lights. The other significant conversion is trading out the old tech TVs for the $7.00 a year (electrical consumption) LED TVs. To sum up: Low electrical consumption .. Excellent light (better/brighter than incandescent) .. Short term expensive & long term thrift. NEVER replace another bulb (lazy). You can now hang your hat over the lamp shade! I'm not off the grid but I am next door to it.TV off the inverter, not shore line. Someone has to create a fix for microwaves...
