I was believing you until you said "cordless cellular window shades" now I'm all NOT SURE IF SERIOUS

(although being able to open / close my window shades by phone might be nice)

:huh:  Cellular shades, per se.

The ones we have are pretty cheap (like $80 for two 2x5' windows, shades cut to custom width) and aren't tremendously insulating, but they look nice and work well.  They have a spring mechanism in the . . . upper body box thing . . . so that the shade has a neutral balance at any position.  No strings; you just pull them down or raise them up, and they stay where you left them.

You can't peak out through them like you can with Venetian blinds, but they look better, stay cleaner, and probably last much longer, since they have far fewer moving parts.

But then.  We were at Home Depot on New Year's Eve (yes, rockin' the party), and for $32 we got a 4' pretend-T8-fluorescent fixture that's 2100 lumens of near-daylight for under 20 watts.  Well, OK! 

I wonder how those would do for plant lights? I bring my potted plants inside for the winter and use 4 old T8 fluorescent fixtures. I have some gro-light bulbs, but most of the bulbs are just cool white. I imagine the spectrum of the LED would be better. I don't have a point of reference for the 2100 lumens though...
It's symbolic of our struggle against reality.

You'd have to look it up.  Most of the fluorescent-style LED bulbs I see are cool white or nearly daylight, but some are warm.  They might or might not be especially plant-friendly, though, regardless of their color tone.

They do sell grow bulbs in that format, but they're often not that pleasant as room lighting.

Daylight runs about 5-6000K.

Most bulbs list a temp. I know all the LEDs I purchase at work do. Clients request warm/cool light all the time.

Not sure this will have much effect on plants, though. Don't they need UV light too? That's a totally different thing than the color spectrum.

I guess that's pretty much what axe said.
you'd be surprised how much a nutsack can stretch. you have to stretch it yourself, not a woman. they don't do it quite right.

Not all UV is created equal but briefly, no, plants don't really need it. Except in the context of bees, who can see into the near UV and certain flowering plants have markings that only show up when UV illuminated that appear to be cues for bees.
If you're growing plants indoors you don't need bees, and probably don't need UV.

In terms of color temperature, the lower temperature sources with redder light are going to be marginally less efficient than bluer lights just because a lot of the chlorophyll b absorption band is in the blue. That might matter some if you're using dimmer light (outside there's plenty of light and plants generally have strategies for dealing with too much light more than they do for too little) (except for forest floor shade plants) (anyway)

We've had those for about 15 years now.  The Dog TV one though has a big chunk taken out of it though.  Thanks Chunk.
