Quick test of 5630 vs 2835 LED strip lights.... - Model Railroader Magazine
Good idea testing them by eye. I've found the color temp by description is completely wonky for LED strip lighting. I'm using some right now that is described as Warm White, but it's the same stuff that used to be Daylight from the same vendor.
A good idea to match to the room lighting. You may eventually want to consider going with light strips up there. I've done that and the difference is outstanding, even though I was running Chroma 50 equivalent tubes. The best part is the lack of heat, which makes a big difference with ops sessions.
Two passes through will work with most scenes with decks close together. I have more of a nolix. The only actual lower deck areas are still lit with flourescents, although those will eventually get LED light strips, too. So my scenes are probably a little deeper and taller. I did have to add an additional pass thrpugha few scenes to get them really well lit, but that's so easy to do I advise people not to sweat it until they're got the lighting all up to see whether it works or needs a bit more intensity.
