Reddit mentions of Bloom Works with Amazon Alexa, Smart Lighting

Sure - it's called Philips Hue. http://www.amazon.com/Philips-456210-Ambiance-Starter-Generation/dp/B014H2P4KW/ref=sr_1_1?ie=UTF8&qid=1453929243&sr=8-1&keywords=hue

That's the starter kit with three bulbs and the wireless bridge (required). I got a Bloom (http://www.amazon.com/Philips-259945-Frustration-Personal-Wireless/dp/B00I12YFP0/ref=sr_1_1?ie=UTF8&qid=1453929363&sr=8-1&keywords=hue+bloom) as a christmas present and then I got another pair of them marked way down on a site that accepts my Amex points so they were like $40 for both.

The app basically listens through your phone's mic and adjusts the color and brightness of the lights according to what's on screen.

Looks like a single Bloom is $60 on Amazon:

I think the strips are the best option for behind screens. You can always cut them (don't recommend) or corral the extra length somehow. I use adhesive hooks behind my TV for the lightstrip.

You can also look into the Hue Blooms, I know they are a popular option to light up the wall behind a screen.

I think the spotlight Hue would do the job.

Your question doesn't make much sense, but i'm guessing you mean something like this?

You can get ROLLS of remote controllable LED lights online. My husband and I use them for lighting our computer cases for instance. Just do a little research in the reviews to make sure people have a good experience with their safety and longevity for the price. https://www.amazon.com/LEDwholesalers-Changing-Flexible-Controller-44-button/dp/B0040FJ27S

If you are looking for an easy solution around 100 to 200 give philips HUE a try? You can control with your phone and they have a couple of products that provide ambient lighting. https://www.amazon.com/Philips-259945-Bloom-Frustration-Free/dp/B00I12YFP0/ref=pd_sim_60_5?ie=UTF8&dpID=41j4KdlKf9L&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&psc=1&refRID=YGM42E2837A7BAV7AW3M and this https://www.amazon.com/gp/product/B00F0W3CI0/ref=s9_dcacsd_bhz_bw_c_x_6 and they have lots of other hue products too.

You could build up a crown moulding with a small shelf before the ceiling then line it with rope lighting to create a lit ceiling. https://www.youtube.com/watch?v=YaSHR6mfbRE

You could buy a couple of lamps from ikea, craigslist, marshalls, tj max, home goods, then put lower wattage lights (40w or 25w) in them on the 2700 (warmer) side of the spectrum. Dimmable lamps would be a plus just make sure the bulbs are dimmable too. They could be standard lamps, wall mounted plug in lamps, pendants you plug in then hang from the ceiling or even something more zen like a salt lamp: https://www.amazon.com/YYout-Himalayan-Crystal-Dimmable-Electric/dp/B01DP47SDY/ref=sr_1_2?ie=UTF8&qid=1469690772&sr=8-2-spons&keywords=dimmable+salt+lamp&psc=1


You can put any pluggable light on a remote with a light switch remote. They can be pretty handy... Or the clapper lol. https://www.amazon.com/Etekcity-Wireless-Electrical-Household-Appliances/dp/B00DQ2KGNK/ref=sr_1_7?s=hi&ie=UTF8&qid=1469690399&sr=1-7&keywords=plug+remote
