One of the most common questions that we get asked is: "How much light do I need for my kitchen?"
The answer, as always, depends on both you and your situation.
One quick question to ask yourself is: "Will I be relying on these lights for the sole source or the primary source of light in the room?" Also, be careful here about windows providing lots of additional light in the space because a good part of the time that you might actually be turning on the lights is when the sun isn't shining.
If you have lots of additional light such as recessed lighting or hi-hats that provide additional lighting for the space, you could definitely go with a lower wattage bulb such as a 4 watt LED which is equivalent to approximately 30 watts of light.
However, if you'll be relying on these lights as the primary light source for the space you might want to consider upgrading to a brighter bulb such as the 8 watt or the 10 watt filament LED in your pendant lights so that you aren't in the dark so to speak.
Also, consider yourself and your age when you make the decision. If you find that your eyes just need more light or you are a little on the older side, sometimes a little extra light can be a great investment since all the bulbs are dimmable and 2700k.
