Good morning, all this is levano lux tv backlighting set, which i got from lidl and it was 30 off now. Why would you want to put backlighting leds on your tv? I know you can get those phillips teles, but those ones light up the same color as what's on the screen, this one, you set the color with the remote control. So if you're watching a fast paced action movie, it's going to be a lot of work to try and follow the approximate color on the screen and apply it to the back lighting set. Nevertheless, let's open this up and take a look at it, break the seal and we're in what we got inside here.

So what have we got? Well, we've got the led light strips and there's a usb plug on them. They've all got individual little connectors. We've got interconnecting cables, uh three interconnecting cables with, i guess their mail connectors and then in this bag there are some little interconnections which are male to male like the cables, but not as long. That's weird look at this thing: that's a sticker.

Why would you want a sticker to replace this sticker here? See it's the same shape that goes around there? Why would you want to seal this box back up? That's really strange! Here's the remote! It's got a little pull tab on it, so that should be up and running right now, let's put some usb on this and see if it works. So these strips all the same length, they do appear to be all the same length. Those three are and then this one yeah they've all got the same. Oh well.

Actually now this one looks a bit. No, maybe it's the same length, i don't know, but this one has got the usb cable on it and also that - and that looks like a little infrared. Is this infrared? Yes, it's infrared uh receiver on it and on the board. Here there is a microcontroller there and three transistors, which presumably drive the three lines to these rgb leds.

Let's power it up, so does anything happen when you switch on the usb. Yes, the leds come on in a sort of white color and all the functions work on this remote control off on brightness down that works, brightness up, red, green blue and then all these other colors all work, yellow purple, and then we've got a flash which seems To flash between the 16 colors is my guess: strobe, i'm not sure what that does probably doesn't do any. Oh, yes, it is doing something slow. Flash maybe fade.

Does that do a fade? Oh, it's doing something. Oh! Yes, it's moving from blue to red. So that does something and smooth that also does something so yeah all the functions. Work on the remote control and that sensor, which is pointing in the opposite direction, seems to be quite sensitive on either side.

So now, let's try one of these connecting blocks. So that's the end of the illuminated section: let's plug that into there. Oh, it's a bit tight! Oh it's too, tight! Why won't that go in oh yeah, it's gone in and then plug that into the beginning of the next section, just checking that all the labels match up yeah. These are just turned: pin uh, ic sockets, so yeah that works um with the little connectors or, of course you could use the little.

What are these one for 300 millimeter ish connecting cables? You could use them as well. Now what would happen if you put this connector on the wrong way around, which is entirely possible to do well, we've got positive here running to positive there, and then we've got rg and b, so they must be grounding pulls. So you pull each of the rg and b to ground. There are three resistors next to each led, so that you're not pulling positive directly to ground.

Now, if you swap this over you're, going to put positive straight on blue um, what would that do red and green will simply swap over? Yes, blue? Would attempt to pull positive to ground because there's no intervening resistor so that could kill the blue channel. It could yeah so here in the manga, it says, connect the led strip, one using one of the two connection. Options choose between the flexible connector or the direct connector when connecting the pole on the led strip, marked plus, must be on the side of the flexible connector marked with the arrow, ensure the correct polarity, but it doesn't say anything about it will be destroyed. If you don't do that, so i'm just going to connect up the final piece of led strip, because you do get four pieces and there are all the leds going through one of their smooth fades and now put it on the flash pattern.

And i can see: we've got red, green blue red and green, green and blue red and blue, green and blue red, green and blue, so eight different combinations, seven different combinations. Actually shall we have a close-up look at one of these leds. Let's uh bring that down. Put my magnifying glass on there: oh, we can't see that very well uh.

Let's make it dim. So that's on static white uh, the dimmest setting. Can we see those leds um? Well, you can see the colors in the sort of um chromatic they're, not chromatic. It's a sort of uh distortion through the lens, it's very hard to get the camera to see.

Oh, that's, perhaps the best i'm gon na get red, green and blue. It's obviously strobing, because the camera's interfering with it i'm just going to try this exposure control. Oh yeah: let's take that down to its minimum yeah. How does that look that looks much better.

Doesn't it we can actually see the red grain and blue elements in there. The three resistors going to the three leds are 201 201 and four seven one now do you think the four seven one the higher value resistor is on green, because green typically looks a lot brighter than the other two colors, so yeah, i'm guessing 471 is on Green, although they're laid out on the connectors, grb or brg with red in the middle and the middle resistor is the 471, but i'm not sure that that means anything. So there we are, that was levano lux tv back lighting set, but you don't have to use it just to backlight a tv you could use it for all sorts of things. Um for mood lighting for self-adhesive, led strips with the total length of two meters.

16 cylinder six single color options and adjustable brightness four color. Changing programs with adjustable speed, usb connection with one meter, cable, easy to use remote control includes battery. This item is for decorative lighting only do not use for room lighting or as a night light. In other words, don't leave it switched on for very long periods of time, and i think the original price was six pound 59 or something like that with 30 percent off.

It was four pounds something, but i can't remember the exact amount, and this is fun - look uh it's on white. If i turn the usb off, it goes on and comes back to white. If i put it on red and turn the usb off, when you turn it back on, it comes back and remembers the color, so it must write that into the uh flash area and not flash the non-volatile e-square prom area of the microcontroller awesome. I wonder how many right cycles that chip's got so, let's switch it off with the off button.

Oh that's interesting when you do that, it briefly goes red before going off. Cheerio.
