For under-cabinet lighting, the first thing I’d look at is the actual light output, not just the wattage on the box. What you want to compare is lumens per foot or lumens per meter, because that tells you how much usable light the strip really gives off. For most kitchen counters, a moderate-to-bright strip is usually a better choice than a decorative one. If the strip is too weak, it will look nice at night but won’t help much when you’re chopping vegetables or reading a recipe.
Color temperature matters a lot too. In kitchens, many people like something in the 3000K to 4000K range. Around 3000K gives a warm, cozy look, while 4000K looks cleaner and more task-focused without feeling overly blue. If you go much cooler than that, it can start to feel sterile. If you want the lights to match existing ceiling fixtures, it helps to compare color temperatures before you buy.
Also pay attention to color rendering, often listed as CRI. A higher CRI, usually 90 or above, makes food and finishes look more natural. That is especially useful in a kitchen where you want the lights to show the real color of produce, meat, and countertops. Lower-quality strips can make everything look flat or slightly off.
The physical build of the strip matters just as much as the specs. For under-cabinet use, I strongly recommend using aluminum channels with a diffuser instead of sticking the strip directly to the cabinet. The channel helps spread the light more evenly, reduces visible dots, protects the strip, and gives a more finished look. If you want to avoid glare, place the strip toward the front edge of the cabinet or in a channel angled toward the backsplash, depending on the effect you want.
Make sure the power supply is sized correctly. A strip may seem simple, but the driver or transformer has to handle the total load with some margin. If you are running several sections, check whether the system supports daisy-chaining or whether you need separate power injection to avoid dimming at the far end. This is where a lot of cheap kits fall short.
Dimming is worth paying for if you use the kitchen at different times of day. Bright for cooking, lower for late-night use. If possible, choose a system that uses a good dimmer and not just an on/off switch. Some strips also let you tune the color temperature, which is useful if you are picky about the look.
Finally, measure your cabinet runs carefully before ordering. It is better to plan the layout first than to buy a random kit and hope it fits. If you have experience with specific brands, mounting methods, or power supplies that worked well, those details would be really helpful.
