Ambient background bias lighting - does it make a difference?

[frank_t]

Hi folks -

I recently purchased a 6500K backlight to mount behind the TV. The set is a 46" XBR4. The light is about 24" I think and has a baffle on it to adjust the brightness.

Anyway - was curious how people have mounted lights behind their sets. I can certainly velcro it to the TV, which seems like the best choice at this point, but curious what others have done.

thanks in advance.

Here's what I have:

It's the ideal lume standard...

I would like to hear people's thoughts on this as well. My Sony 40" Bravia set is positioned at a window. This makes the set look pleasingly dark during the day and short of moving somewhere with permanent daylight, I'd like to replicate this effect with lamps, etc for night viewing.

I had enough space behind my tv on the stand itself so I just placed my backlight there. Simple and easy. A nice glow from behind that is slightly heavier at the bottom and gradually fades upward. It's pretty.

I used the velcro for mine since I didn't want to screw anything on the tv... And it holds well!

Here are some pictures that you see the lights (Ideal-lume panel light mounted on each side of the tv) (I'll try to get a better picture for you tonight!)

Can someone explains the point of this light?
Is it just aesthetic?

yeah the light actually reduces eye strain when watching tv in the dark. it can also improve the perceived quality of the picture. white is the best option for doing this as it simulates daylight, the blues greens and reds that you see people use have the same effect as white but are just more pleasing on the eye, plus it looks cool when you have buddies around

I mounted mine on the wall on either side of the set

I see, thanks.

[househead]

if you use velcro don't use the stuff that comes with the idealume. It's shit compared to other brands.

Stop by Home Depot and get some heavy duty stuff. Be safe!
For only a few bucks.

This is my bedroom set up its at the foot of my bed so i dont have it up against the wall so it lights up the whole room but i love it this way.

We have the Ideallume and it actually rests peacefully across the mount bar of our Z-Line Phantom 50 stand. This pretty much centers the lume for our Sony 46W3000. It illuminates just enough top, sides and bottom. No children in the home, plus the hubby and I are just careful around the entertainment area. 6 months and haven't had to adjust it once.

I was thinking of getting one of these lights, however my T.V. is mounted right onto the wall, with no space behind it.

Could I just put this under my T.V. like behind the credenza??? I'll attach a picture so you can see it.

Also can you get these lights in Canada anywhere?? Thanks

question about these lights.....

always heard people who had the "Ambi-light" t.v. (can't remember what the brand was) and they all loved it, bought the t.v. because of it, etc....

I get the "eye strain" and "preceived increase PQ" thing.....

so my question is,

"Does the same thing apply for Front Projectors" ????? Obviously you don't want a lot of light... but will a little red/blue/white behind the screen (but not shining on the screen, so running lights around the back of the frame of the sceen, and making sure the light can only go to the OUTSIDE of the screen, and not to the inside (if that made sense) so the light diffuses outward....


anyone know?

thanks!

The only part I can answer is the first, which isn't even the question - they are Philips Ambilight TVs (proud owner of one), the feature is fantastic, sure you end up with lesser blacks because it's a Philips, but it does actually ease eye-strain, turning it off mid-film is quite a shock! It doesn't increase PQ, lol, but the ambilighting does serve to give the illusion that black levels are darker. I didn't buy the TV because of it, but it is a feature that all of a sudden I can't live without - and when I upgrade my main TV, the Ambilight feature is going into the bedroom.

But as for your actual question - I have no clue.

You can install it directly behind the tv (on the support or on the tv).

Look on the cinemaquest site:

I ordered mine from the Cinemaquest website, it was shipped by USPS (then Canada post). Shipping was slow and cost $32.16 for the panel lights. Everything arrived in one piece and I had to pay taxes (TPS and TVQ). I don't know any local dealer.

Cyron also makes some.

A cheaper and easily available alternative would be the Dioder from Ikea. They don't have 6500K bulb but they aren't that bad...

From the article in the "FOR FRONT PROJECTION DISPLAY SYSTEMS:" section of this website, the same thing applies...

Screen brightness can be overdone. Too bright of an image may induce eyestrain during extended viewing sessions and necessitate backlighting of the screen. This is very difficult to implement without light reflecting back onto the screen from room surfaces.

I guess the difficult to implement part, requires the help of a custom installer who knows what he's doing!

Thanks for the link! I bet I could make it happen, what I'd do, is "box" the back of my screen with wood, so the light can't go through the screen, and just paint the walls VERY Flat, dark (in a dedicated room, I can do what I want) for acoustical treatments alone, I was thinking about lining the walls with something, I'll consider just doing the wall the screen is on, and the ceiling, covered with black felt perhaps (that may look good if I do it right) we'll see.....

Might have to look into this. I enjoyed the pictures. I think I can make it work really nice with my set up.

[quexos]

Yep it's Philips that does the ambi light. it's more than just a light behind the tv, it's a color changing light, it goes with the colors on the picture. The blacks are good in my experience (but then I have a last generation Philips).

The 7432, the 9732, or the new 3603/5603?
