I struggled for years to find a lighting set up for my work from home environment. I eventually realized that it was the quality of light not necessarily the quantity of light I needed to address. On a whim, I purchased two of those plant grow lamps with full spectrum, lighting, and pointed them upwards perched on a tall pedestal reflecting off of the ceiling. This has worked far better than any other lighting strate…

Glad to hear someone else doing this. I feel bad not using the grow light to... you know... grow plants. But the light it provides in my office is lovely.

Any lens can be customized for desired focal length, including distance, intermediate (e.g. computer) or closeup/reading.

Right. It's an industry term though and doesn't have anything to do with focal length.

Consumers develop their own interpretations and usage of industry terms used in marketing to consumers.

Just get modules or strip from Yuju; I have zero bad experience over many years with them. Sure, it's not cheap, but IMO ~1$/W plus simple PSU (either some standard voltage, or dimmable current, depending on what you got) for good and 1.5~2$/W for very good CRI is quite fine.

Yuji looks quite good, thanks. I need to see if I can integrate this with my DMX/Zigbee lighting control.

Unless you want individually addressable LEDs, the answer to the "if I can" is "yes".

This is worth considering in the context of driving at night. I used to get terrible eye strain, causing fatigue and sleepiness. Obviously not good. Then I bought a Saab 900. It had a 'night mode' that disabled all dials except the speedo. The lights went off and the dial went down. (It came back on if it needed to alert you of something, say low fuel.) [0] This made a radical difference, and led me to the dash-brigh…

Are there any cars that DON'T have a way to adjust the brightness of the dash lighting? Every car I've ever owned (86 Chrysler, 2000 Suzuki, 2016 Subaru, 2019 Tesla) had a dial to adjust the brightness of the dashboard lighting, or in the case of the Tesla, adjust the brightness of the screen. Sure, I couldn't completely shut anything off like your Saab, but I could easily turn the brightness down pretty dim.

It seems if you turn the dial all the way to the left on the Toyota Camry (and maybe other Toyotas and Lexuses), everything will disappear except for the gear position.

How would this compare to something like the Godox LA 200D, which claims an output of 100,000 lumens? I use two of these lights on tall stands pointed at my ceiling, which seems to work very well

They claim 101,000 lux, not lumens. Lux is light per square meter (roughly), lumens is total light output. The closer you get to the source, the higher the lux will be, so it's hard to compare lux equally. Based on their 230W power draw and typical COB efficiency, I'd guess it's 20,000-35,000 lumens. Tldr, we're brighter, fanless, have adjustable color temperature, smart home compatible, and more aesthetic.

Appreciate the response!

Note that most IPS displays have 0 PWM flicker. I use a couple IPS gaming monitors. IPS displays look better for code vs OLED anyway, IMO.

Yep, I use IPS monitors for this reason. Gotta avoid PWM to help prevent the headaches I experienced on other types. IPS looks really good too, so that works out.

I'm in a basement and had fairly good success with certain "led shop lights" to make the space feel more like it has natural light (though I could improve things further). I do find however, that using diffuse lighting and minimizing shadows is what makes lighting feel artificial. Natural sunlight has very parallel rays that create very evenly lit surfaces with very sharp shadows. Whereas most artificial light has ra…

I've been wondering for a while now if our indoor lighting is too dim. Even in the shade during midday you're looking at 20,000 lux. Overcast days look dark and dreary and they're on the 1000-2000 lux range. Meanwhile home lighting is well below the 500 lux range, if not even in the 100-200. I even suspect that the current near-sightedness epidemic is caused by people spending too much time in dim lighting. Maybe if…

> I even suspect that the current near-sightedness epidemic is caused by people spending too much time in dim lighting. Maybe if our indoor lighting was brighter our eyesight would not adapt to become near-sighted as much.

It's not that eyes are adapting to low light so much as the fact that exposure to 10k lux stimulates the release of neurotransmitters which prevent the eye from growing too quickly. Last I checked, the recommendation is for children to spend 2+ hours per day outdoors in sunlight. Morning and evening aren't sufficiently lit so it really comes down to school and after-school care scheduling enough outdoors time.

A big thing not often spoken about with eye strain is dry eye caused by the lack of blinking due to focusing on screens too close to our face. This is an evolutionary phenomenon--close dangers cause extreme focus without blinking. Extreme focus on close items reduces our blinks. Our eye lids have glands in them that release oils on your eye with each blink. These oils help prevent the watery part of your tears from e…

Pretty nifty, except that it also detects "winks" as "blinks".
