OK, so after getting my OEM projectors functioning, I decided to upgrade the bulbs. So I went to BulbFacts and, based on their reviews, ordered a set of DDM Sabre LED 75W Max series on sale for $167 down from $230. On the order form it asked if I wanted a decoder box. Since I had not seen anything about decoder boxes on the forum threads, I said “no”. When the bulbs arrived I found that the bulbs did not seem to fit the socket (need an adapter ?) and that there was a box in the wire connector wiring. Have no idea what this could be but I will return them. Can anyone recommend a good LED that is compatible with the OEM projector housings that is simply plug and play ?
