Like I posted earlier in this thread, I also found that the goose neck hanging lights I had installed were not bright enough for my tastes to light up the interior properly.
My solution was to install LED strips on the underside of each of the rafters running lengthwise from front to back. I purchased pre-wired LED strips with resistors, such as the ones below, that can be powered with 12v-18v AC or DC power.

I bought a bag of Plastruct U-Channels (about 1/4" wide, I think) to first mount to the underside of the rafters in order to hide the LED strips and painted them brown to match the wood-colored rafters in my RH and cut them to length. Since they come white and your rafters are white, you probably wouldn't even need to paint them. I trial fit the adhesive LED strips into the channels (they're snug, but fit) and secured with CA glue and glued the assembled channel to the rafter underside and then ran the red and black wires out the back and down the wall tucked in close to the uprights and then out the bottom of the RH to be hooked up to a power supply. I also painted the wires brown to blend in and you would probably want to paint the wires white before installing.
The channels, led strips and wires are virtually invisible to anyone viewing the RH. They provide plenty of additional "hidden" lighting and I was completely satisfied with how it came out. One of those deals where more than likely only you will know they're there.
If you think you want to try this route, let me know. I have almost a full bag of the Plastruct channels that I'll likely never find another use for that I can send you.
