On the 4 ampoules, 2 operate only. The first was never turned on. The second, only the LEDs light up the outer circle, the third works well, but the heat made the LED plate is detached from the bulb (but that does not bother me), and the fourth it, works perfectly. So assessment 3/5 as only half of the bulbs actually work. This is unfortunate because the light intensity of those walking is pleasant, less annoying than conventional bulbs but good enough to light (say at 80% intensity compared to conventional bulbs). Nice soft light.
