I’m in subtropical, so warm and wet. My parents have mostly yellow lighting most of my life. I didn’t really have a strong opinion until I bought a home and had painted 3 walls before I stepped back and realized I hated how the paint looked on the walls. The minute I changed out the light bulbs from the 3000k to 5000k, suddenly the light gray/white paint looked more gray/white and less magenta (apparently had 1/64th magenta in the formula and I could see it with the warmer lighting).

I prefer higher K due to the very real effect it has on cooler colors and style of my home. Also much easier for me to actually see.

If the dimmer has a range of 5w to 100w, can I only dim the load down to 5w, for example a 10w light down to 50% (which is 5w)?

I'm curious: what part of the world are you in? Turns out there are some strong geographic preferences that are often (not always) linked to local climate. People in deserts tend to prefer high-K lights, and people at high latitude tend to prefer low-K lights—both the opposite of what they tend to see outside.

Warm light also matches natural lighting more closely - at the hours you’re typically relying on interior light. High noon is closer to 4000k light. Sunset, sunrise, and low angle sunlight is warmer - which is when you’re typically relying on interior lighting. Warm light is for cozy, relax hours. Cool color light is for mid-day active hours. Most smartphones have the option to auto-shift the screen color temp similarly. Places of work and shopping centers typically have cool white light to promote alertness. Restaurants and spas use warm light to promote relaxation.

But do what you like!

Agreed, I’ve slowly been swapping every light bulb/LED panel with bright 4000k dimmable light bulbs

Yellow lighting makes me want to puke, our carpet is grey so it makes it look like it has pee stains with tired eyes and our walls are blue so it gives them a green tint

I hate anything below 4000k. Yellow lighting is atrocious imo, and I can never see as well vs whiter lighting….but yellow does match better with traditional aesthetics. For a modern style and cooler colors in a home, 4000k - 5000k works great. It’s not only for shop lights. Lol

Load is always written on the side of dimmers, usually 1000 watts. Let’s say 1000 wats/14watt led equals 71 of those little fuckers

I agree. You only need to divide if the dimmer didn’t explicitly say for LED. Divide by 10 is a quick and dirty conservative way of converting incandescent rating to LED rating.

5000k is sharp cool white. If this is for a residential application you should consider something closer to 3000k. If this is a workshop or similar 5000k makes better sense. That’s my .02.

The load is fine. You were correct in adding up the points. If you have trouble with dimming (flickering, etc) you might need an LED compatible dimmer.

You had it right, just add them up. You can use 10 14W lights. The divide by ten may have meant to get what size light if you wanted ten of them or something like that

Your dimmer is fine.

The division has already been done for you.

3/4 inch plywood can hold up to 500 pounds

1/2 inch to be safe.

What thickness do you recommend?

You could put a piece of plywood up as a mounting block so you can place it anywhere. If you're picky about how it looks, you can stain/paint it, add some trim, make it round/oval like a medallion, whatever look you prefer.

Bolt the plywood to structure on two or more beams.

It has keystone, but looks worse when I use it. After all keystoning lowers the resolution. Making a square out of a trapezoid means you're not using the full resolution. I'd like it to be as straight as possible

Does your projector have a keystone setting? You may be able to center the image without moving the projector.

I'm no pro, but I've painted a decent amount of shit now. First I paint my walls, then i took a paint stir stick and hold it against the ceiling, draw a line every few feet. Then I tape up to that line, so it should leave a ¼" line between the tape and the ceiling. Then paint your ceiling and it will make a nice straight white line on the wall. But this way if your ceiling is wavy or off in any way, it doesn't show, it makes your ceiling look straight.

Yellow paint or nicotine?

If it's smoke residue, you'll have to clean it off, or hire a professional company that can. Otherwise it will just bleed through the new paint.

Use frog tape to tape plastic down and edges. Remove light switch covers and outlet covers (tape over the moving parts and holes). Use and edging tool first and multiple thin coats are better than fewer thick coats.

Get sample colors and paint small sections on the walls. Watch for 24 hours to see the color in all lights. If the horrible color bleeds through, do a layer of primer first, or get a paint with primer built in. Use a high quality roller and remove lint by wrapping masking tape sticky side down around it.

When you are painting, be barefoot (easier to know you stepped in something)

Buy good quality brushes and rollers! Purdy is a good brand and well worth it!

Couple things:

1.) how dark is the yellow? 2.) what color are you changing to? 3.) get off TikTok 😂

If the existing color isn’t too dark you may get away with a coat or two of a high-solid content paint, depending on the new color. I would recommend using a primer anyway though.

When it comes to the actual act of painting, you’ve probably seen best practices on that in your research. A good rule of thumb is to zig-zag to cover, then back roll for uniformity. The most important thing is to make sure the last stroke of the roller/brush be in the same direction across the room

When you're trying to paint a straight line, watch the tip of the paint brush (and the paint moving down it ) and not the surface you're trying to paint. Sounds so simple but it made a big difference to me.
