We converted ours twice, once to the warmer colors and then we changed some to the brighter colors. I have recently added an extra bright four bulb LED array over the table.
Even when I purchased the LED lamps with the most available segments the TT is not as bright as I would like. However, the LEDs are much better than the incandescent TT lamps and I would never go back but the wattage is limited compared to the 120 volt LED bulbs I use at home.
Lately my I saw an LED shop light that was very bright that I may try.
I will admit that when sitting around the camp fire I like nothing brighter than a candle lantern but inside the TT I like it bright. :)
I have not had any issues with interference with my television though some folks have.
I also found the 10 and 20 LED bulb packs shipped from overseas and sold on eBay cheap enough to experiment with.
Good Luck
