Dynamic Lamps

Brought this as spare for my Epson HC 4000, so far have not have to replace so, can't tell how good or bad it is, so can only give 3 stars.

I can only rate it at 3 star for now. Brought these as spare, so far OEM bulb have not burnt out yet. SO I can't tell how good they are at this point.

The lamp they was shipped from dynamic lamps was inoperative. When we installed it into our fixtutre it did not light up right out of the box. I took another older bulb from an identical adjacent fixture to test the fixture. My old existing bulb lit up in my future who's bulb had burned out. I also tried the Dynamic Lamps ordered bulb in another fixture and it still didn't light up. When I went to my local vendor where I had purchased the fixtures he (for free) gave me a brand new bulb to replace the faulty Dynamic Lamps bulb. I won't use dynamic lamps anymore :(

I am not very happy because I still do not have the light I order on 1-16-17 and I chose 3 day shipping because I really needed the light but yet I still do not have it.

There's a line on the TV from the bulb. We ordered the expensive bulb for the reason we wanted a clear picture. That didn't happen picture looks ugly with the line on the screen.
