Good LEDs, after quite burned more ... Here they are cast in a kind of gel, which should help distribute the heat probably. The design is good, heat is low and the shape of the bulb is really suitable to replace the original halogen bulbs (unlike the Chinese flat). But LEDs, although many here are really powerful too little. One advice: use only for decorative lighting in furniture, for example. In any case the most satisfying I've had in terms of quality.
PS: come in a pretty box (thumbnail) card that is reminiscent of the box of conventional bulbs with the power in lumens etc. This small detail is however very reassuring for the customer.
