We are the manufacturer of MediaLight and the only authorized seller on eBay.  Our warranty does not apply to purchases from unauthorized sellers (who usually charge more than our retail price). 

Finally, there's a bias light in a convenient LED form factor that doesn't make you sacrifice colour accuracy. And everything is included in the box, including a wireless dimmer.
