Wow, so many opinions on inexpensive LEDs. Here's one more: Nearly 2 years ago I replaced every single bulb in my RV with LEDs
Here's the details.. That's more than 25 bulbs. Total cost was less than $125, even including the 18' strip on my awning. Some with bulb style, some with flat panel style, many with at least 48 individual LEDs, EVERY single one of them were cheap LEDs from Amazon and eBay, NONE of them had current regulators (which can and do cause RFI). I use them both while boondocking, as well as with full hookups (up to 14.5V). I have checked temperatures; none have exceeded 225 degrees after several hours at 14.5v in ambient temps of 90+ degrees (which coincidentally is less than HALF of the temps of an incandescent). I have measured very little difference in either current or temps regardless of whether I am running at 12V or 14v. And I have not had a single failure...not ONE. I have several friends who have done the same as me. And many on this site (and others) have had the same experience.
I spent very little, cut my current by 80%, increased my light output by at least double, DECREASED the temperature of my fixtures, have NO interference on my TV or radio from RFI...and yet by reading this thread you'd think that I would have burned my RV down by now since I didn't pay 5-10X more for LEDs from CW. Yes, SOME cheap LEDs are bad quality, but not all. Where do you think that CW buys their LEDs prior to a 500-1000% markup? :?
