Also, any experience with the company?

For the price I would totally try them!

All my LED's are from iJDMtoy.

Prices are totally reasonable;

Packaging is adequate; and

Shipping costs and delivery times are competitive.

I've had no issues with them and would shop from them again in a heart beat.

Generally, bulbs like those have reduced light output because they are colored blue to tint the warm halogen light into a cooler (temperature) looking output. All of those types of bulbs are most likely made in China/Korea/Cambodia/etc, so the quality is going to be about the same as anywhere. Not sure which lights you're looking to replace, but I'd look into an HID conversion kit (for headlights) or LED offerings from various vendors here (for any other bulb except high beams and fog lights).
