LED Bulbs

I replaced all eleven yellow, dim incandescent lights in the MH with $8 each LED. I did not select warm, I bought the brightest LED I could find and they are great. Those that say there is little difference, did not do the research. There is a huge difference, you get a bright white light.

I liked the LED's so much that I went to Home Depot and changed my home outside 40 watt incandescent lights to 60 watt LED's on sale for $6.97, now back to $10. I had a total of 480 watts of lights turned on by the security light detector. I even replaced the security flood lamps with LED flood lamps, $27. Now the security detector turns on all the same lights only at 100 Watts of power, and just as bright as they were before.

Nice write-up and nice results. I'm wanting to do my workbench at home with LEDs, and am considering the new 5630 LEDs. They are supposed to produce 85 lumens per watt (vs 65 for your 3014 units, 55 for the 5050s, and 44 for the 3528s). The strips I used inside were the 3528 (600 per 5m), and the panels I used were 48-5050, so the 5630 should be fantastic as a workbench worklight! The color of yours looks to be more of a pure/bright white than warm, more in the 4500-5500K range (warm is usually down around 3500K). Personally, I like that bright/pure. I don't care for the yellow "warm" nor the blueish "cool". Your 3-LED "nightlight" idea is great, as well! Very cool!

Thanks Ron. Very interesting.
I was wondering how the new 3014 LEDs compared to the old 3528 and 5050 LEDs. It seems the new LEDs draw more current but are substantially brighter than the 3528s.

From what I read and understood, the newer LEDs draw less current per lumen produced. I added more LEDs than most people would consider enough.

One thing I have in the back of my mind. It takes but a minute to cut a 3-LED circuit off each strip while installed in the fixtures. If done, in our case the lights would actually be more balanced to the fixture with darker sides and lit centers. So later, if my wife and I jointly agree that the fixtures are just too bright, I could get it done one 3-LED segment at a time quite uneventfully, even during a trip. Very easy to take away but work to add. With every 3-LED circuit removed, the power will drop by about 1/3 of a watt.

Looks real good Ron. Have you had a chance to measure the current drawn by one light?

No I have not measured a completed fixture. To get current-draw (wattage) figures from my place of work, I only brought in one 11 segment (33 LEDs) strip and one 1 segment (3 LEDs) strip.

Amperage measured at 12 volts....
The 33 LED strip calculated to 4.17 watts
The 3 LED strip calculated to 0.312 watts
Remember there are two 33 LED strips per fixture

The engineer and I found it strange that the 33 LED strip was so much more than 11 times the 3 LED strip. It is hard to determine why so much a difference. We'd would accept some variation, but not 20%. I am thinking of bringing to work my surplus material for more measurements but taking measurements would require cutting my surplus strip into 33 LED samples.

If considering the 3 LED sample, each fixture would be rated at 6.8 watts, not 8.3 watts. It is around half that of the florescent lights, maybe even 20% better yet. I also feel that if you wanted to reduce the strips from 33 LEDs to 27 LEDs, the lights would still illuminate effectively, especially with lighter colored interiors. I max'd out with 33 LED strips because of our dark cherry cabinet finish. A little more light seemed the better idea.

Apparently it is as vague as fuel economy. I accepted that I won't really know how much power consumption was reduced, just happy it is a lot less along with more light, a warmer color tone, and also now having the integrated night-lights.

Okay, I completed my LED conversion over the weekend. Here it is in a nutshell.

The original florescent light fixture with everything florescent removed. It all pretty much just snapped out.


The LED strips installed. I selected the angled surfaces for they had a flat surface to bond to, and to direct the light outward


Note the 3-way switch in the center/off position. Also note the tiny 3-LED circuit. The main circuit has 66 LEDS, 33 per strip.
Note the other long surfaces had raised lettering which did not offer a flat surface to bond the strips to.
I sure hope the strong adhesive backing will permanently hold them in place.


Here the light is turned on. The camera adjusted the exposure. It shows how the light gets dispersed.


Here is a picture I had taken for comparison. A florescent light is forward and a completed LED light farther back.
The blue tone florescent appears to be just as bright, but it really is a little less.


Here, all fixtures have the main 66 LED lights on.
The room is actually a lot brighter. The camera adjusted the exposure.


Here, only the 3 LED night lights are on.
The camera adjusted the lighting. It actually has a nice soft glow throughout


I am disappointed in that the camera could not capture "True" lighting. Full-On appears much darker than actuality. Night-Light shows it much brighter than actuality. Sorry about that.

Here is the sealed LED porch light. I made a reflector from some industrial aluminum foil, not for food handling, very very stiff. I cut and shaped it to fit behind the bulb and around the sides of the fixture. You can see how the light bulb has a larger illumination. It seems to be a softer light, I think because the LED bulb is frosted and sealed.


Cost as follows.

- $12.05 on Ebay for a 5 meter length of LEDs in a reel. Because I made the strips as long as possible and having the night lights too, I was one strip short. I bought a second reel to have enough. Only one reel is required if having 27 LEDs per strip, assuming 9 fixtures.

- $8.42 for 20 3-way switches purchased off Ebay, though I only needed 9

So theoretically one can convert 10 fixtures for $12, straight & simple florescent to LED. That is a real bargain. I tripled the investment to just over $30 to have a little extra light and to have the night-light feature. I do have a lot of leftover material on-hand in case something fails later. You do need to have fairly good soldering skills and a lot of patience. It took me an entire day to convert 9 fixtures with the night-light option added.

- $30 per pair of sealed & frosted LED bulbs. I used 5 in our rig.... Shower, Closet, Outdoor Storage, Porch, & Sanicon.

One final project is my range hood light. I could use some left-over strips up inside the hood cavity, but favor changing the socket and use that 6th spare sealed bulb. I could mount that bulb directionally downward toward the stove to be more effective.

Don't get the ones I bought...lol

I received the LED strings & 3-way switches & initially completed one fixture. I really liked it so I did all 9 in our motor home. Now we have more light using less power, and each has a mood/night light as well. The light is white, not yellow like the picture above shows. We like it better than the florescent blue we always had. The LEDs brighten up our interior with the dark cherry cabinets. It was an all day project to get all 9 fixtures converted.

Pictures will follow as soon as I get some time for it.

I removed the light fixture over the kitchen sink and removed all of the florescent electrical content simply by unclipping and unsnapping things off. I did have to use a soldering iron to remove the circuit board because of the way the on/off switch pierced through it from behind. Everything could easily be reassembled back to "original" if my lighting conversion is not satisfactory.



Though the reel of LEDs have not yet arrived, I got a jump start on this because I am locating a replacement switch from a single click to a double click. Center being "off", one direction being full lighting. The other being only a tiny strip of LEDs for mood/night lighting.

Here are the dimensions I need to find a physically same size replacement 3-way switch. They are sold very cheap on ebay, 10 for $6.00 but unfortunately they are not stating dimensions.
