Overview

Design. The 28mm SMF2 LED bulb is a direct replacement for any 28mm-size bulb commonly found in vanity mirror lights in many vehicles. Populated with two 5050-size SMDs the SMF2 upgrades the factory yellowish incandescent bulb to a more modern LED appearance while adding far more total light output than the factory bulb. The SMF2 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.

Brightness. With 24 lumens of true measured output the SMF2 LED will provide about double the total light compared to your original 28mm-sized bulb. 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 SMF2 is available in a cool white 6000K and warm white 3000K option as well. Whether you want a modern cool white appearance or a traditional warm white color we have the color to fit your need!

Edger Does Not Fit The 52CC Trimmer
Style: 9" 2T Cutting Blade
Might be a great cutter head?? I purchased the 52cc trimmer and edger as a package, however the edger does not fit the trimmer??? Therefore, it is useless... Will see if it fits my 25cc trimmer and maybe change the review... They should tell people in the description that their edger will not work with the 52cc trimmer....

Cut edges like a pro
Style: 9" 2T Cutting Blade
Better, much better than the OEM yellow and black brand. This has an all metal guard and the blade does not bind when it comes into contact with concrete. I have used it all summer for edging two commercial properties and my own lawn, it’s still turning and cutting with ease. Being all metal adds weight but the trade off over fragile plastic is worth the durability.

OK for light duty use only
Style: 9" 2T Cutting Blade
Not very strong or robust. Does fit my power head properly. Only recommend it for occasional, light duty use.

These work for the Worx trimmer WG928
Size: 16 Line Spools+4 Caps, Size: 16 Line Spools+4 Caps
Recently purchased the Work String trimmer and blower bundle. I found these and ordered them in hopes they were the right ones. They fit and work perfectly. Super easy to install. Pop out the old one and pop in the new. The string is pretty durable and thick. I love the idea of pre loaded spools. It got so annoying having to rewind the string on the spool every time I ran out. Price is fair and worth it. Highly recommend these if you have the same trimmer.
