<p>Installed a few 30mm cutout mini COB spotlights under our kitchen cabinets and in display niches. 3W each but the beam quality is impressive - clean, focused light with no glare.</p><p>What I learned:<br>- 30mm hole saw makes the cutout, takes 2 minutes per hole<br>- These need a recessed housing or can be pushed into a 30mm drilled hole<br>- 3000K warm white looks best for accent lighting on wood/tile<br>- At $3/piece, cheap enough to experiment with placement</p><p>They're also great for: bookshelf accent lighting, jewelry display, hallway niches, bathroom vanity.</p><p>Product info: https://www.lrleds.com/products/15</p>
