HelicopterOff Topics › How-To: Convert 4' fluorescent tube shop light to LED

This thread convinced me to convert the 12 (2) tube fixtures in my shop. I converted one as a test and I was hooked. Ordered additional bulbs but they are currently on BO. Should be here shortly though.

One of the main reasons for conversion is the horrible quality of the currently available fluorescent bulbs. Even more expensive ones vary in intensity from bulb to bulb and they just don't have the lifespan then once had. This and the much improved light output from the LED replacements makes going that route a simple decision. The much lower energy usage is just a plus in my case but I won't be complaining about the relatively quick ROI.

I'm not sure whether anyone is still following this thread or not but here are a few more bits of info about my conversion project.

Again, I have (12) 4 foot, two tube fixtures in my workshop. For my now complete conversion, I chose the 20W, 6500K milky tubes. Dang, these things are bright and even getting into the blue light spectrum a bit. The verdict is still out whether this color was the best choice or perhaps I should have gone with the 4000K version. I think I will adjust to what I have though! The wife really likes the bright light and wants me to convert the lights in the kitchen.

A plus for the conversion is the energy consumption. I measured the power used by my old fixtures with 40W fluorescent tubes and the whole fixture consumed 95W so there is a good bit of inefficiency there. After the conversion, the same fixture consumes right at 40W which is less than half the previous use.

A minus for the conversion is ..... these LED lights create shadows! Because the light only comes from the front side of the bulb unlike the fluorescent tube's 360 degrees, the fixture's reflector is now pretty much useless. The direct light from each LED bulb creates individual little shadows around everything the light is cast on. There will never be a 100% resolution of this problem but moving some of the fixtures around a bit should minimize the issue. A minor problem for the most part but a problem that did not exist at all with the fluorescent tubes. By comparison, the shadow problem is similar to when incandescent bulbs are used.

My fixtures had the electronic ballast eliminator circuitry so conversion time was a bit longer than a conventional fixture. I can still convert them in about 30 - 45 min. each which is the time from removing them from the ceiling to reinstalled and making light.

I'm quite anxious to see how these work out long term but first impressions are quite good. Did I mention .... dang these things are bright!

I am not sure the right terminology is "polarization", but the light coming from the LED fixture seems to be tightly focused.
Where as the florescent tube's light is diffused and unfocused.

If you place you hand close to a surface with a typical florescent tube fixture, your hand has to be close to the surface before the clear edges of your shadow is defined.
Do the same with the LED fixture, and you get a very well defined shadow from a much larger distance.

I notice it when I an looking down the inside of a tailboom.
At the perfect alignment with the LED light source, the inside of the tube get brighter than a florescent tube.

Don't be afraid to mix and match color until you get what you like.

Buy a couple 4000K tubes and mix them with the 6500K tubes in the same fixture.

In the kitchen, I would recommend the 4000K.
I put some 6500K tubes in there and my wife got depressed at how all the dirt showed up on the stove.

I have several 4000K tubes here I am going to mix with the 6500K to see what the results are. (24) 6500K tubes are really too much bright light for my shop and I need to tone it down a bit.

Doing some research today, there are filters on the market to accomplish the same purpose. LED lighting is a very different animal than most of us are use to dealing with and some experimenting will be necessary.

You can also remove 1 tube from some of the fixtures in selected areas of the shop.
I did this in some of the remote areas of my shop and it works out pretty well.

I have my light strings on separate switches so I can darken part of the shop when I don't need light in certain areas. I tried removing a few tubes but the shadows became a problem.

As of today, I'm adjusting to the bright light and really starting to like it. Changing the light source reminds me of adjusting to new glasses. It takes your brain a bit of time to adjust.

I checked the power consumption for the whole shop with the new tubes and my two tube fixtures are averaging 38.5 Watts which is well down from the 95W with fluorescent tubes. Seeing those numbers helps me adjust to the new and different light!

A dimmer might work with the led lights....
I have a porch led light that will dim for dusk to dawn, suppose to be half output, and brighten on movement, i didnt think the led would dim down but it will....

The led light might be in series to equal 120v on a diode, if so you can dim the lights

nitro fun, the type of LED tubes we are working with are designed to be connected directly to the AC power line. They work with a line voltage anywhere between 85V and 265v and have small power supplies built into a heatsink on the back side of the bulb. They are not dimmable according to the company literature.

I am considering LED lighting for the kitchen and the fixtures there will require special tubes that require a separate DC power supply. They are still very energy and light efficient though.

Thought I'd chime in and say that I converted my single 4' fluorescent in my heli trailer (6'x10' to LED and the difference was astonishing. Way brighter and when at the field I'm limited to the 1650w continuous power that the generator puts out so every extra watt counts.

ticdoff9, mine are still going strong and working as advertised. In a few months, if they would fail for whatever reason, I'll have saved enough in electricity costs to pay for the conversion. I was even able to sell my old fluorescent tubes on Craigs list for $.50 to $.75 each which further financed the project.

The only issue I had was the extreme brightness and color of the new tubes but I adjusted to that quickly. I would hate to go back to conventional lighting!

Old thread but its been just about a year since I changed my shop over to LED bulbs and I continue to be pleased with my decision to make the change. Most of the problems I thought might exist have pretty much gone away after I adjusted to the different kind of lighting. Thanks to the OP for starting this thread or I probably would not have made the change.

Great info TruckRacer. Now you got me to jump in!

Just bought 4 of the 1200mm 20W (2400L) 6500K in milky to try out. Got them from same eBay seller (ledking*us) at $10/tube delivered.

Try Butterfield and Digital Drive on the north end. Enter next to Velodyne Acoustics.
Or, the field on the western side of Ann Sobrato HS. Enter next to Hallmark Equipment (go around the gate).

My LED lights are working great.
I had one, last, florescent fixture that was in a kind of hard to reach area. It finally died.
At this point, I am 100% LED inside the house and in the garage.

When I first finished, I thought about sell the 30+ tubes I had.
But, I just wrapped them in tape and took them to the recycling center.

Awhile back, a guy came into my shop and the first thing he did was look up at the lights and said .... "WOW, those lights are bright". I told him they were just right for aging eyes!

I replaced the refrigerator last year. The old one broke, so I had no choice. This new one is more efficient and tighter.

The recent rain's washed off the panels. So I am getting more production per hour form the panels than I was last year.

I traded in the '11 Leaf for a '15 Leaf, and it is more efficent than the '11 by a long shot. Getting a real 80 per charge now.

I also replaced more bulbs in the house with LED.

All this resulted in a $20 check from PG&E at "true up" this year (not really a check - but a credit on the bill).

I think I will replace my gas water heater (new in '04) with a new electric water heater to see if I can balance out the over-production this year.
Electric water heaters are cheaper and it will lower my gas bill.

There are 2 ways to rewire the fixture and I chose the easiest.
1) You cut out the ballast
2) Wire the "Line" (black wire) to all wires from all the tombstones on end #1
3) Wire the "Neutral" (white wire) to all the wire on all the tombstones on end #2.
Done.
That was in the original post on page 1

Some do not have ballasts.
They use a transformer and an electrolytic capacitor on each end of the fixture. Just open the end caps, cut out the transformer and cap, and wire directly to the tombstones.

What the best place to buy some 4 ft. LED tube, Cool White, 120 VAC. I plan to remove ballast and rewire fixture for 120 VAC tube. There are so many types and source; I am having difficulty finding 120 VAC tubes. What wattage is a good choose?
Thanks.
