I happened to be looking for LED strips today. The conclusion – detached from the feel: The brightness is really huge – up to just under 5,000 lm per meter. However, it also requires a well-planned electrical system, up to several power supplies per strip and maybe a few decentralized "proper" power supplies and drivers if you don't always want to run at maximum brightness. Last but not least, you have to consider that not only light is emitted, but also heat, which must not damage the components, so you must also pay attention to a suitable cooling. For all these reasons, streaks will only appear occasionally.
