Keep your other other ESP8266 set up and verify that commands you think you're sending are being received. I know you already did this, but if it was in isolation from trying to control the bulb, a connection may have loosened later on. ...
I already love a very similar module, the nRF24L01+ (see “Tutorial: Nordic Semiconductor nRF24L01+ with the Freescale FRDM-K64F Board“). The ESP8266 looks is similar from the size and connection header, but instead of SPI it uses UART mode with AT commands. So it is much more like ...
