Yes, they will be nice to use.
But I really want is nanobionic light-emitting plants. Not a joke, found on the last page of Photonics Spectra February 2018. I subscribe to this fascinating magazine.
MIT says plants may be desk lamps and street lights.

I think for most purposes, well chosen LED light is good enough to start installing rather than previous FL or LED alternatives or holding off. Costs will come down some, but probably reliability as well.
Right now, I'm using 90+ CRI led hyperikon tubes for my retail area.

Better than fluorescent, better than most screw in bulbs. Photos shot with cell phone look great, as that seems to be the type of camera most finicky about poor CRI lighting and least able to compensate with awb. The transition from North window natural light to LED light is very smooth and doesn't make for bad photos.
I also... I love buying and using light bulbs. I have too many, i gave away all my CFL. Not liking those one bit.
I installed a dozen of these. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
One went blinky, documented elsewhere on this forum, but I have a spare case.
I like a very white light in my workshop. Reminds me of my wife's old studio.

One thing I like about the Hyperikon units is you can run them without the ballast and get even more savings on the electric bill. Putting them in my shop I got twice the light using half the electricity as the flourescents. I like the 5000k color too, looks more natural.
Re: SunLike LED inside the home, studio, streetlights...
When low-E lighting was mandated, it stuns me that the health risks were not weighed first. There's an epidemic of middle age cataracts (vs old age) due to computer screens and E-lighting. CFL's are an interim technology, and most of em are utterly junky, and burn out just as fast as cheapo ordinary light bulbs did. There are still ways to bootleg tungsten bulbs like using heavier droplight bulbs. The stupidest thing is them allowing hot halogen bulbs but not ordinary tungsten. A lot of houses have burned down and lives have been lost to that idiocy, esp combined with Cheapo Depot floor lamps that fall apart if an aphid lands on em. I had to wear sunglasses in my office until traditional chroma tubes showed up. The owner had doctor's orders to remove the low-E ones. He almost went blind. I pity these kids who grow up with electronics screens instead of puppies n kittens.

I buy http://lightbulb.aerolights.com/view...e-20-000-hours
Very nice bulbs. Menards stocks them.
Made in USA
Re: SunLike LED inside the home, studio, streetlights...
There's a bulb at a small rural fire house in this area that's been continuously burning for 115 yrs. They knew the importance of heavy filaments and thick bulbs way back then. But of course, the mfg soon went bankrupt due to lack of repeat sales.

This looks similar to Yuli's technology: https://store.yujiintl.com/ .

Spectrum graphs look different, but both stress violet/purple is key.
Re: SunLike LED inside the home, studio, streetlights...
On a tangent - does anyone think these types of lights could be strong enough to make Pt Pd or Gum which require high intensity, high UV wavelength light.??
