I have 2 of these installed along a wall (each can be switched alone, but I can only upload 2 pics, so I show both on alone and both on with the others in the living room environment). Both together, when on, consume only 22 W, but give powerful yet warm lighting to their area and actually are doing a work of around 50W ELs or 250W of incandescent bulb.
They do not radiate heat the way other lighting elements do. After being on for over 30 minutes, you can take them in your hand and the warmth you get is like the warmth of a cat when you pet the cat's belly. The area that has the electric contacts to go into the socket gets no heat at all, it stays in room temperature. For installation inside various closed elements that specify max wattage allowed, you can put these regardless of whatever limitations of this sort, as those limitations apply and refer to incandescent bulbs and the most powerful of these LED elements will never get to the minimal limitation. Heat just doesn't take part in applying these, unless you want to heat the environment with them. For this, they are a bad choice :-) .
The room the pics I attach were taken in, is a 4MX7.5M living room. One is with only these on and the other is with them and others on all together.
