LED 12 volt lighting: Long term results
Well, my 24 and 36-LEDs arrived yesterday from Hong Kong. It was dark by the time I got back from the mile long walk from the mailbox and right away I ripped open a 36 and installed it over my kitchen counter, stove, & sink area.
Here are my comments/findings:
1) The units are smaller than I pictured them, but so what.
2) The wires on them are incredibly puny but I can cope with that.
3) The bayonet fitting is some kind of mini-plug that doesn't fit my 1156 type sockets. So I just cut the wires and taped them into the circuit.
4) The amount of light from the 36-LED is FANTASTIC! One 36-LED completely illuminates my entire counter-stove-sink area wonderfully! I am not used to regular 110 volt lighting and hate it because it's generally so bright when I visit normal peoples' houses that it hurts my eyes. But I would compare this 36-LED to about a 60-70 watt bulb, or so it seems to me.
5) From my amp-meter reading it appears that the 36-LED burns about 1/4 amp or just a tad more. I can easily live with that!
6) From the amount of light this 36-LED throws, I plan to mount a 24-LED over my kitchen table. That should be plently of light and why waste power with a 36-LED when you don't need to?
7) The BIG QUESTION now is how long this relatively "cheap" ($9) LED will last in daily useage. My previous LEDs started crapping out within a year or so and did not live up to the hype. While old time incandescent auto bulbs simply NEVER burned out in my 12 volt stand-alone solar electric & battery system (well, almost never).
8) One problem/question: Since the wire leads on these Hong Kong LEDs are so puny there is no good possibility of soldering them into the circuit like I typically like to do. I guess I can tape them on but here's a question:
QUESTION: Is there any kind of electrically conductive glue-cement-adhesive on the market you can use instead of solder to make a permanent electrical connection? This would seem to be a no-brainer since no melting heat or dripping solder would be involved. But does it exist? If it does I've never heard of it. But how cool would that be? Just wrap the wires together and coat them with the conductive adhesive and then tape it. Presto! A perfect permanent connection! Useful, but does it exist???
I plan to update this thread by-and-by with long-term results of these Hong Kong LEDs as their reliability and longevity is unknown. Please post your own thoughts and experiences with ("cheap") 12 volt LED lighting as this is new and exciting but still pioneer technology. But if you can find good ones that don't break the bank, they are the way to go.
Thanks for clueing me in about these LEDs from Hong Kong. I don't know if I'd of found them without the help of people on this forum.
