I won't suggest specific products (local availability is patchy), so I'm going to be more generic: The main thing is that there are non-visual receptors in our eyes that are used for determining the level of "daylight", and they are most sensitive to light around 480nm [1]. To give the right signals, you want to match daylight's intensity in this part of the spectrum at day, but gradually decrease it to zero in the late evening. You can look for lightbulbs or LED strips that come with a quantified measure of melanopic vs standard lux (it's sadly not common), or you can look for light sources that come with a graph of the emitted spectrum (a requirement for the new EU energy efficiency label!) and make an educated guess. Generally, 1800 K or colder(/"warmer") LEDs will have little of the melanopic component, using "monochromatic" orange LEDs is also an option (both dimmed appropriately).
