Re: LED lights Reply #1 – August 15, 2005, 10:13:54 pm Yahoo Message Number: 56868"go to www.surefire.com for a bunch of flashlights" We were talking about wired-in light fixtures (e.g., reading lights), but SureFire does have what look to be high-quality flashlights. However, before buying any LED flashlight, I recommend a trip to the LED Museum website (http://www.ledmuseum.org/>), where you'll find hundreds of hands-on reviews of every conceivable battery-powered LED device. You'd be surprised at how some of the deluxe models are really just so-so...and how some of the cheapies turn out to be champion performers! The webmaster, a retired electrical engineer, puts each unit through its paces and is candid about the results. The LED Museum is where I found out about the remarkably good $1 LED keychain lights (http://www.countycomm.com/light10.htm>) that I've been giving to my LD-owning friends for the past couple of years. I love these amazingly bright little flashlights! In fact, I gave one yesterday to David Forness of this group, who was staying with his companion René here at Ocean Wood campground in Birch Harbor, Maine. (They left this afternoon, headed north to Eastport.) David and René tipped me off to this place when I left Eastport heading south, and we met here. It's magical! I've added a record to the campgrounds database, but It's hard to put into words how wonderful this place is. I planned to stay a day, and ended up staying a week and a half. David and René planned to stay a day, and ended up staying almost three weeks. It's that kind of place.Andy Baird
Re: LED lights Reply #2 – January 01, 2013, 09:59:57 am Yahoo Message Number: 135934If you are good with a soldering iron and tools, and have a few hours on your hands, you can replace all the lights with LED's for less the $100.: Search on eBay search for . That should get you to rolls of LED's that can be cut to length. I bought 1 roll of cool white and 1 roll of warm and that was enough to do all the fixtures in my MB using 2 strips cool and 1 warm per fixture.I used these to convert the incandescent fixtures: http://www.ebay.com/itm/160889326349?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 using up to 3 to 5 of them for the fixtures I wanted brightest (like the one over the bathroom mirror, and only 1 for the light in the shower. Note that with breathing protection, you can use a grinder to 'remove' one row of LED's on each end of the board to make the board short enough to fit within the night light fixtures near the floor. 3 are attached to a thin piece of plastic (cut from a white milk jug) to fit inside the lens cover for the porch light. Note that the bayonet socked adapter provided in the kit is too small to fit the socket in the LD light fixture, so the sockets were removed and the LED board plug and pigtails wire in directly (solder and shrink tubing insulation).For the florescent fixtures, I used one roll of this (two strips for each light fixture) : http://www.ebay.com/itm/150945313310?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 along with one strip of the warm white LED's (3 strips of LED's for each light). Note that even though I cleaned the mounting surface of the light reflector with alcohol, it was necessary to also glue down the ends of the strips with a hot melt glue gun to keep them from coming loose. I did every fixture except the two over the bunk, as we never use those, though I have enough LED's left over to convert them also.bumper[Non-text portions of this message have been removed]

If the seller doesn't give any color temperature, you can assume the LEDs are blue-white (euphemistically referred to as "cool white")--typically 5,000' to 6,000' K-- and you probably won't like them.Andy Baird The Hollywood movie 'standard' for daylight at high noon is 5,500' to 5,600' K. I don't agree with Hollywood on much, but for this it's just fine by me. When I'm sitting at the dinette trying to see fine detail, my old eyes prefer something closer to daylight over a warm incandescent light. If I want to get cozy I'll break out the candles (g).bumper[Non-text portions of this message have been removed]

Seems to me I've read that as we age, our corneas gradually take on a yellowish tint, so a cooler, bluer light may compensate, and thus actually work better for older eyes. I guess I haven't reached that point yet, but I probably will sooner or later. :-)Andy Baird

That is the beginning of a cataract. If we live long enough we will all get them. I see many in my current job.
