The most powerful of these is only 3W, which it says replaces a 60W incandescent. Nowhere near powerful enough to replace anything that actually uses a lot of power and would be high-mounted. Maybe if you have a chandelier full of 60W incandescent bulbs, which since this is Dubai we're talking about, is actually possible.
Yes that could be. Most recessed lights I've seen recently are spotlights, although that could be a function of where I am looking.
IMO, interior designers and light manufacturers need to work together to make attractive energy-efficient lighting solutions. For example, recessed halogen-based spotlights are a nightmare for LEDs - there's nowhere for the heat to go. Even if you get an LED bulb from aliexpress, it won't last long because of the lack of proper heatsinking. Meanwhile there's plenty of surface area that could be utilized for heatsinking if the fixture is designed for LEDs from the ground up.
The higher wattage units need good heatsinking, and I believe that is easier done with integrated units, where the "bulb" aka driver is not replaceable. I've also thought of making my own, with a strip of aluminum and mounting 1W/3W emitters to it myself. Easy enough to drive them at whatever wattage you want, and maintain good thermal properties.
