Home made louver cover retrofit for CFI wrap light - PLANS!

Home made louver cover retrofit for CFI wrap light - PLANS!

Click to view full size image

I came up with this idea after looking at my wrap fixtures. I realized its easier to make louvers for my existing fixtures rather than ever finding any real louver fixtures.

This picture is a sketch i drew of what it would look like. I know having them 3D printed would be best but thats not an option i have.
The louver in the drawing is designed for the CFI wrap as a retrofit option. No modification to the fixture itself is needed, just place the louver on.

The louver would have 8 tabs on the top (4 on each side), 4 of them on one side would be movable and the other 4 stationary. Simply hang the louver on the 4 stationary tabs, then close the louver cover and close the 4 tabs on the other side to secure louver to the same ridges on the fixture that the wrap would go.

A space between the top of the louver and the fixtures sides where the tabs are allows some light to shine up to the ceiling

Can anyone recommend a type of plastic thats easy to work with but is strong? Id prefer if it was white plastic that allows light to pass but solid white is good too.

Sorry for poor writing on the paper. I cannot write very good lol

I'm also thinking of what circular louvered covers for 2 lamp circuline fixtures would look like. They would have the same design as conventional louvered fixtures but instead of a V channel , a centre cone would be in the middle with baffles protruding from it with a slight separator in the baffle between the 2 circuline lamps.

Your handwriting is great. Mine is a bunch of scribbles lol. I've heard that some louvers are made of metal. Mike has one with metal louvers.

Metal louvers are the way to go. Aluminum is lightweight and easy to work with and will hold up. Then you can used ribbed white acrylic for the ends and sides.

Any suggestions on how to cut sheet metal or aluminum (whatever I can find at a large hardware store)

Nice drawing! Best I can figure off-hand if you don't have access to a band-saw is perhaps a good pair of tin-snips. That may be tedious and tiring, however, depending on the type/thickness metal you are trying to cut. Finally, some sheets of medium grade sand paper taped to a flat surface such as a sheet of glass or very smooth table. Then glide the metal parts across the paper to get smooth edges and get rid of dangerous sharp burrs.

Very nice drawings. Great idea, makes me want to find some commercially.

To cut sheet metal, you may have luck at a sheet metal shop (duct work shop) where they have the equipment necessary for cutting sheet metal. If you supply them with detailed drawings of your parts, they should be able to cut them. After assembly, a couple of coats of spray paint would complete the job.

Depends on thickness. Thin Aluminum (which is actually whats used in most louvers nowadays) can be cut with simple scissors... That may be actually better than big metal cutters as they will leave clearer edges

Yeah cutting out the louvers should be the easy part, but I have no idea how I will make the V channel. The metal would have to be bent all the way down the middle and the louvers need to go into slots but not sure how i will make those. This will definitely be a lot of work since I need to make 3 of these

You don't need a V part. Just have a straight single piece touch the ballast channel. My F90T17 louvered fixture doesn't have a V section; it's just a single vertical piece.

But the V channel was one of my favourite parts But you are right, its much more easier to have a single piece and I suppose that can work

Would a wooden V-channel be an option ? It might be easier to make than a metal one, and it doesn't need to cover the ballast as the fixture's existing ballast channel cover would remain in place. You could then paint it in any colour you like.

Ah I see. Yeah the V would give a more authentic look. If you use really thin wood I suppose it could be done, but it would have to be very thin to fit right.

I'm not sure what is your budget and how far you're willing to go, but here's a company that makes louvres for troffers although they are in the Czech Republic. I imagine they're very expensive, considering the shipping. There is a white V-shaped louvre that I think is the look you're after.

Thanks! , that is a nice looking louver they have, i bookmarked the page. Im not sure what budget is yet but cheaper the better. I have not thought about using wood, that may work pretty good. Just having a simple vertical piece would have to do and thinking of it it doesnt sound bad. I'll draw it out and see how it looks

V channel making : Clamp the plate at the edge of a rectangle cross section rail or beam, and bend down to 90 deg. After it is 90 deg, put the L shape on the floor, push down the corner with a thin board, reversed baking tray etc to bend it a bit more to under 90 deg

Unfortunately I have no metal working tools to do such at this time. However I have slightly modified my design and decided to consider making it out of wood. Preferably a really light weight and easy to work with wood type. Mahogany maybe ? Lol

Making it out of wood would make it look very good with certain decor. I would not paint it as i'll just use the lightest colour of wood possible

The louvers can still be light aluminum painted white, with the vertical strip being a thin piece of wood that matches the sides . This could look very beautiful. The side edges of the louver blades could be inserted into the wooden side panels for strength and security. I will start looking for materials next month

Check this place out. They sell louvers and baffles pre-made. If you find one you like, you could work around that. This style in particular looks like it could work.

For the louvre blades, you could use old Venetian blind slats. Metal ones are curved but some plastic ones are straight. Just a thought.

For wood, I'd probably use pine as it works quite well and is light in colour (although it tends to darken with age and UV exposure).

I didnt think of that, thanks! I may look into those for future projects. I already bought tin snips and will be looking for the wood and aluminum sheets this coming weekend. If all goes to plan, this will turn out awesome. I plan to work on them extensively starting this weekend.

"Unfortunately I have no metal working tools to do such at this time"

Dont really need any. Any rectangle shaped metal beam, wood board and some c clamps thats all

"Metal ones are curved but some plastic ones are straight. Just a thought."

Some high end louvers actually use parablic curved "blinds" in them. The Venician blinds are more curved than lighting needs, and are round instead of parabolic, but their roundness does not make them inappropriate (any more than non light reflecting materials like wood....)
