Explain. Isn't a dimmer switch just a variable resistor? Do you need fancy dimmer switches if you want them to work with LED bulbs?

Old-school dimmer switches were rheostats, and they got hot. Pretty much all dimmers now are TRIAC-based, which is a semiconductor that turns on partway through the AC wave, then turns off at the next zero-crossing, repeat. It chops the waveform so the light only gets power for a fraction of the time. An incandescent bulb works largely the same with either type. (You may hear the filament "sing" on a TRIAC dimmer sin…

> LEDs should be driven with DC. But there's an awful lot of installed fixtures to keep us from that utopia.

Every LED luminaire or lamp already has a DC inverter inside of it.

Also, you can get (158) 28w 2x4 LED fixtures on a single 277V 20A circuit with #12 wire, DC lighting branch is never going to happen. For reference, that will light about 12,000 square feet of space assuming 9’ AFF for ceiling height.

A lot of the guidelines that are used to light a scene for a camera are also quite useful for lighting a room for yourself, just with less light needed as the human eye has a much higher dynamic range than a camera sensor: * Use diffuse light. This usually means multiple light sources bouncing and diffusing light off surfaces (ceilings, walls, etc) or diffusers. * Minimize shadows. Shadows lead to contrast which can…

In the history of LED lighting, it took quite a bit of work (hybrid phosphor technology, etc) to get them to emit warm color temperatures. The exact color temp can be a personal preference, but I think a lot of people aren't privy to the difference the color temperature of "white" light can make! I want to go on a guerrilla campaign around my neighborhood and replace porch light bulbs with warm equivalents.

Along light temperature there's light cri as well, which measures how faithful to real life a light is. New standards such as Tm30 came out recently as well

Environmental modification is one of my favorite emotional coping strategies. It.. feels like you're actually doing something! Cleaning up/tidying, "sacred space creation," light and color therapy all work way more effectively than you might believe.

Talk to me about color therapy

Nature bathing is great. But it turns out that people in hospital beds facing windows recover faster when they face nature. And, in fact, it's not the nature at all! It can be fake and just as effective. In the end, basically, it's the green.

Color therapy or chromotherapy is incorporating specific colors into your environment to evoke desired emotional states. It blows my mind how well this works, and that's why you see peach colored walls in offices.

Light works similarly. Warm vs. cool, etc. You can use light exposure to regulate mood, particularly for conditions like seasonal affective disorder (SAD). All of this is culturally-dependent but it works way better than you'd think.

Here are some of the common color associations:

1. Red Emotions: Energy, passion, excitement, strength, urgency, love, anger, aggression.

Therapeutic Use: Stimulates energy, increases heart rate, and can evoke strong emotions. Often used to combat fatigue or lethargy, but excessive use may lead to overstimulation or agitation.

2. Orange Emotions: Enthusiasm, creativity, warmth, optimism, sociability, joy.

Therapeutic Use: Encourages social interaction, boosts creativity, and uplifts mood. Often used to combat depression or feelings of loneliness.

3. Yellow Emotions: Happiness, clarity, intellect, optimism, caution, anxiety (in excess).

Therapeutic Use: Promotes mental clarity, stimulates the nervous system, and enhances focus. However, too much yellow can lead to feelings of anxiety or frustration.

4. Green Emotions: Balance, harmony, growth, renewal, calmness, peace, envy (in some contexts).

Therapeutic Use: Known for its calming and balancing effects, green is often used to reduce stress and promote relaxation. It is also associated with nature and healing.

5. Blue Emotions: Calmness, serenity, trust, stability, sadness, coldness.

Therapeutic Use: Reduces stress, lowers blood pressure, and promotes relaxation. Often used in spaces meant for rest or introspection. Darker shades can evoke feelings of sadness or detachment.

6. Purple Emotions: Spirituality, luxury, creativity, mystery, introspection, wisdom.

Therapeutic Use: Encourages deep thinking, meditation, and spiritual connection. Often used to inspire creativity and self-reflection.

7. Pink Emotions: Love, compassion, nurturing, calmness, playfulness.

Therapeutic Use: Promotes feelings of warmth and comfort. Often used to reduce aggression and create a soothing environment.

8. White Emotions: Purity, clarity, simplicity, peace, emptiness, sterility.

Therapeutic Use: Creates a sense of space and cleanliness. Often used to promote mental clarity and a fresh start.

9. Black Emotions: Power, sophistication, mystery, fear, sadness, protection.

Therapeutic Use: Can evoke feelings of protection and strength but may also lead to feelings of heaviness or depression if overused.

10. Brown Emotions: Stability, reliability, warmth, comfort, dullness.

Therapeutic Use: Grounding and stabilizing, often used to create a sense of security and connection to the earth.

11. Turquoise Emotions: Calmness, clarity, communication, emotional balance.

Therapeutic Use: Combines the calming effects of blue with the rejuvenating qualities of green. Often used to promote emotional balance and clear communication.

12. Gold Emotions: Success, wealth, luxury, wisdom, optimism.

Therapeutic Use: Inspires confidence, abundance, and positivity. Often used to elevate mood and encourage a sense of achievement.

13. Silver Emotions: Modernity, sophistication, intuition, reflection, coldness.

Therapeutic Use: Encourages introspection and clarity of thought. Often used to promote a futuristic or innovative mindset.

14. Gray Emotions: Neutrality, balance, sophistication, boredom, sadness.

Therapeutic Use: Creates a sense of calm and balance but can also evoke feelings of dullness or detachment if overused.

I was wondering how practical it is to create 3D renders of your room instead of photos for the blog post.

I think I found an answer: in this case, it's insanely practical.

The reason is it's a blog of a senior designer at Shopify. He has the skills to make this easy for him, and showcasing them is smart.

Is no lighting considered too little? I like to sit in the dark with nothing but a computer monitor for light. I have noticed this greatly reduces eye-strain and distractions, but perhaps that is just me.

For me it really depends on the situation. When I'm gaming or watching a movie, I prefer effectively no light. In fact, I built an enclosed space in my garage that is light tight. Then I have an overhead LED strip with variable intensity control. I find that programming and video calls both work best if I have a reasonable level (about 50% of what a typical office overhead would provide). I absolutely love complete darkness but after a while I start to feel like a cave troll.

Are there any communities of others online dealing with general eye strain? Or other blogs / videos that have helped others? I have had chronic eye pain for a while now and could really benefit from hearing what has helped others. I have not found doctors to be helpful I have a pretty normal Dell office monitor but not sure if I would benefit from an upgrade. I have relatively normal overhead lighting and try to take…

The standard 60Hz refresh rate of monitors is unlikely to produce any eyestrain. The refresh rate of the backlight could produce eyestrain and headaches. Unfortunately, the exact frequency of the PWM used for backlight isn't often mentioned in the specs. In general, anything above 500 Hz is better as some people get headaches even for 250 Hz.

Rtings.com measures PWM frequency[1] as part of their reviews.

I am sensitive to bad CRI and color temp(3100K FTW). I really like the cheap "torchiere", floor lamp/uplights on Amazon but am finally giving up on them due to issues with poor CRI. I find standard screw-in LEDs from Philips to be the best, easily available source of light.

Amen. Honestly the IKEA lamps are the best - super cheap and you can swap out the bulbs with high quality dimmable philips. What torchiers are you swapping to?

How do you source lightbulbs? I have yet to find a reliable LED bulb that doesn't hum or flicker on a dimmer despite being advertised as "dimmable" . . .

I actually "solved" the problem by using remote controlled light bulbs. I can still use the switch to turn them on and off, but I have to use the remote for dimming. Not the most elegant solution, but the dimming works flawlessly, and on my model I can also change the color temperature, which is nice, and it was actually cheaper than most "dimmable" light bulbs.

I did this too with IKEA bulbs and their remote control that you can directly pair to multiple bulbs. It works out great, and I don't have to deal with another phone app or buy a hub in my house to manage.

Are there any solutions that involve reflecting mirrors that allow you to add variation to the apparent viewing distance so your eye muscles are exercised more vs staring at the same distance for too long?

Cool idea. Would love to see prototypes of this. This is essentially what happens at an optometrists office when you go for an eye test.
