Parcels received less than 15 days, simple packaging. I installed the LED inside of my 308, slightly blue light, the most beautiful effect. The negative is the leg which is mounted resistance, visible by looking through the small holes on the base. I used a 510 ohm resistor (in parallel) by door opening LED (3 in my case) because of the current résiduel.L'effet Dimmer LED still works. I recommend these LED recess T10.
