A rechargeable lamp runs where there is no socket, which is the whole reason to choose one over a mains lamp. That covers a desk away from a wall, a table outdoors, or anywhere a trailing lead would be in the way rather than merely untidy. Recharging also means the lamp is used and put away rather than being tied to one position.
RGB control changes the light rather than only the colour. A warm setting suits a room in the evening and a cool one suits working, so a single lamp covers both rather than being fixed at whatever the bulb happens to be. Both warm and cool settings come from the same lamp rather than needing a bulb changed to reach either.
Pre-lit trees are chosen by height and by light count together, and the two rise in step. The trees here run 5ft at 150cm, 6ft at 180cm and 7ft at 210cm, carrying 190 to 350 LEDs, so a taller tree arrives with proportionally more lighting rather than the same amount spread thinner. Light count is stated per tree rather than being worked out from the height alone.
Hinged construction is what makes a pre-lit tree practical to own. The branches fold down rather than being fitted individually, so the tree opens out and packs away without the lights having to be handled at all.
