Product Description
E27-x4W-T series is a tubular LED replacement bulb for traditional medium screw base lamps. Light output is comparable to 40~45 Watt incandescent bulbs. Consumes just 7 Watts of power using 84 LEDs. Commonly called a corn light due to the large number of LEDs on this single bulb. Available in Natural White or Warm White with a 360° beam pattern.
RoHS stands for Restriction of Hazardous Substances. Certain materials used in electronics and electrical products have been deemed hazardous to people and the environment and, therefore, must be limited. For a product to be RoHS compliant, testing must be performed and documented to show limited or no use of cadmium, hexavalent chromium, lead, mercury, polybrominated biphenyls, and polybrominated diphenyl ethers.

Reasonable replacement for a piano lamp
It came and it worked, but in a piano lamp one has to be careful to keep the lamp shade rotated such that the LED's aren't in direct view. That's because this lamp is thicker (about 1.75") than the T-10 sausage-shaped incandescent it replaces. Aside from that, it's nice and bright, and my piano teacher seems to like it.
