Do-it-yourself home renovation – window replacement, internal insulation, heating modernization, new bathroom, kitchen, wardrobe – cold and warm flooring

Besides general home renovations – such as replacing cold and warm flooring, kitchen cabinets, and sanitary ware – a crucial point was to create a low utility cost home.

.

Because of this, modern plastic insulated glass windows with shutters were installed, and the previous convector heating, open combustion bathroom heating, and the open flow-through domestic hot water unit were replaced with a single condensing boiler.

Since there is zero chance for common facade insulation in the apartment building in the near future, 10cm thick glass wool internal insulation was installed on the enclosing walls, with a vapor barrier heat reflective foil and drywall covering.

A disappointment may occur if you believe any RGB LED strip photo to be real

Of course, it can happen by accident that we publish a picture of a product that has nothing to do with reality, but it can also be intentional. The problem is that RGB LED strips can emit light in many colors — practically any color of the rainbow. This puts manufacturers in a difficult position when they have to showcase an RGB strip with just one photo while it’s lit. To convey everything an RGB LED strip is capable of, they resort to various image manipulations. This manipulated image is provided to distributors and is also featured on the product’s box (if it has one). Photoshopped images like these are created:

.
Many customers believe that these LED strips can actually produce such lighting.

In the above image manipulation, we see stunning combinations of RGB LED strip colors. Unfortunately, these are not real; they are mere manipulations. There are, of course, LED strips capable of illuminating in every color simultaneously, but these are not them.

Products sold with such photoshopped images not only belong to the group of cheaper and less reliable RGB LED strips, where even the seller doesn’t know what the product is capable of because they’ve never seen it in person or, if they have, haven’t tested it. What I don’t want to delve into right now is that, in many cases, not only can’t these RGB sets achieve the lighting suggested in the pictures, but buyers frequently report issues with improperly sized, overheating, melting RGB controllers, and exploding power supplies, as well as poorly soldered LED strip connections in their product reviews. However, this article is not about these problems; it’s about the misleading representation of lighting experiences and ultimately deception.

What’s wrong with these depictions of RGB LED strips?
