They can look identical on the outside, but they are most likely made of cheaper parts. There is no way you can get authentic Phillips bulbs for that cheap

Best bulb on the market ever: Philip bulb from Nigel-JDM parts cost $260 or something

Yup Philips all the way. Got the best lumen's output for the color.

Garax, bang for the buck but it's lumen is less than Philips.
