LED Bulbs "Super Bright" yada yada yada

[friz]

Well, they are not "Super Bright". At least the ones I bought, 20x Super Bright DC12V T10 921 168 6000k White RV Interior 24SMD on ebay. These are the "paddle" style and inexpensive - 20 for $12 + free shipping. I needed to replace a couple of interior double ceiling fixture bulbs. The installed bulbs are column shaped with LEDs on all 4 sides. I went with the paddle shaped bulbs as I thought they would direct more light down. I was wrong. The column shape light up the whole lens/fixture. The original column shaped bulbs are much brighter. Very few of the vendors on ebay state how many lumen their bulbs put out. So, what have you found to be the brightest bulbs (shape, # of SMDS, manufacturer, vendor, etc)? I am new to RV LEDs. Last time we had a 5th wheel the interior bulbs were incandescent. Also, are they supposed to be that difficult to push into the socket? Is there a special insertion tool? The ones I bought were almost impossible to insert.
