LED T8 Retrofit?
Has anyone done an LED T8 retrofit in a commercial setting?  Are you able to reduce a four lamp fixture with two LEDs without a ballast?  Where did you source your LEDs?  Any advice would be greatly appreciated.

The Landlord agreed to retrofit all four rows of a four lamp fixture with LED's and provide an additional row for only $6000.00. This is a 20,000 SF warehouse BTW. No clue where the electrician sourced them from.", "replies": [{"id": "d0dk4kk", "text": "Did they replace all four tubes with LEDs or did they go from four fluorescent to two LEDs?", "replies": [{"id": "d0dlh43", "text": "Four fluorescent to two LED's.", "replies": [{"id": "d0dlr6d", "text": "Perfect!
