Features Direct replacement for factory 28mm festoon bulb Adds more modern LED appearance Plug and play simple installation Overview Design. The 28mm SMF1 LED bulb is a direct replacement for any 28mm-size bulb commonly found in vanity mirror lights in many vehicles. Populated with one 5050-size SMD the SMF1 upgrades the factory yellowish incandescent bulb to a more modern LED appearance. The SMF1 was designed with an embedded load resistor and implanted diode for superior reliability. With its durable metal terminals it will fit snugly in the socket and its light weight means it won't vibrate loose over time. Reliability. Unlike other bulbs on the market this bulb is built with constant-current circuitry along with transient suppression. That means this bulb will last for years not months with no flickering or failure. And like every Diode Dynamics product it's backed by an industry-leading three-year replacement warranty.

If you are looking to increase output we'd recommend checking out our SMF2 option! All Diode Dynamics LED lighting is rated with accurate measured lumen figures not calculations or guesses. We test the true output in-house and provide you the real numbers to compare. Colors. In addition to vibrant colors of blue red amber and green the SMF1 is available in a cool white 6000K and warm white 3000K option as well.

Great sunscreen, leaky bottle cap
Size: 3.4 Fl Oz (Pack of 1), Style: SPF 50
Great sunscreen. Smells good, but not overpowering. Best mineral sunscreen I’ve used—still a bit pasty, but rubs in better than any other brand.
The bottle design is horrible. The cap falls off with the slightest touch. If you like sunscreen in the bottom of your beach bag, the bottle is great.

Did not protect
Size: 3.4 Fl Oz (Pack of 1), Style: SPF 50
Product smells great and goes on better than most mineral sunscreens. It was labeled as "reef safe" so I assumed it would work well in water. It did not. After just a half hour in the Caribbean water, my skin was red. The product did not say "waterproof" so we decided to use it only when we were away from the beach. Unfortunately, even in the cold spring weather of our northern climate we still ended up with red skin. We had no choice but to throw away the rest of the bottle. Do not expect this lotion to protect you from the damaging rays of the sun.

Great sport block for sensitive skin
Size: 3.4 Fl Oz (Pack of 1), Style: SPF 50
I use this whole playing tennis or pickleball, it might be a little much for everyday. Does not irritate my sensitive skin. Rich enough for dry skin. Very slightly white cast that quickly fades. Does not run or bother my eyes for sports. Basically perfect in all categories.
