AFAIK there are two resistors in parallel on each of those LED bulb, except of in the cheapest ones. If you destroy/unsolder a correct one (with higher resistance), the lamp is going to shine significantly less brightly but with higher energy conversion efficiency and with significantly less heating. If not a correct resistor has been dismounted, the lamp is going to shine too dimly to be useful. PS. I have not tried this livehack yet, so i can not promise it works, but maybe it is important to clarify that my source is talking about 220V bulbs.
