FUNCTION

28mm SMF2 Bulb is a direct replacement for any 28mm festoon halogen bulb. Usually, these are used in the vanity mirror lights of many vehicles.

By changing the factory bulb to an LED, you can illuminate the area with a much brighter light, and add a pure white, luxury look.

The installation is 100% plug-and-play, just replace your factory bulb.

 

BULB DESIGN

This bulb has two 5050-size SMDs. The bulb is made up of a 28mm sized base for an OEM look, as well as high durability metal terminals. A load resistor is embedded to prevent blowing the LED from voltage surge, and a diode is implanted to protect the LED from reverse polarity. The LED is wired for 12V operation, the kind found on all vehicles.

Included in your order is ONE BULB.

 

COLOR

These LEDs are available in crisp, bright colors including Cool White, Warm White, Blue, Red, Amber, and Green.

 We strongly recommend cool white or warm white for the best visibility.

BRIGHTNESS

16 Lumens

Lumens: BUYER BEWARE! Most sellers just provide "calculated" lumen numbers, based on the maximum potential brightness of the LED chips on the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is not accurate, as the design of an LED bulb does not get rid of heat fast enough to run the LEDs at maximum.

These "calculated" lumen ratings are much, much higher than the true, measured light output, so it will look like competitors' bulbs are brighter than ours. This is because Diode Dynamics does not provide inflated "calculated" numbers; we believe it is misleading. We test the actual brightness of the bulbs in our lab, to provide real lumen output measurements. Our measurements are accurate, but they are usually much lower than the misleading "calculated" figures. Please click here to learn more about LED brightness measurement.

 

QUALITY

LED Components. Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means we use only brand-name suppliers such as Epistar, Cree, Osram, and Samsung.

While our bulbs may look the same as others on the market, most copycat bulbs use economy-grade LED chips in order to reduce costs. This greatly reduces the reliability and overall brightness of the bulb when you compare it to Diode Dynamics.

Construction. Although LED technology allows for extremely long bulb life, the market is flooded with cheap LED bulbs that fail prematurely due to inferior construction. The worst enemy of LEDs is excessive heat, and when bulbs are not designed properly, they do not disperse heat as well, leading to premature failure.

Off-brand, cheap bulbs exhibit poor solder uniformity, high levels of flux in the solder, uneven chip placement, low-gauge terminal wires, poor assembly, and bulbs held together with inferior adhesives. At best, solder joints will crack and fail on low-quality LEDs after a few weeks of use. In the worst case, these bulbs can damage housings as the extra flux and adhesive evaporates and creates a residue on the lens of the housing.

Diode Dynamics bulbs are produced with modern, computerized equipment, and only the best materials, to ensure complete uniformity, high quality, and long bulb life.

All Diode Dynamics products come with a 30-day satisfaction guarantee and a 3-year limited replacement warranty. For more information, please view the FAQ guide.

    Bought these after a cheap ebay brand went out after a couple months of use. Way brighter than those and they just feel a lot more durable. Would highly recommend these bulbs to anyone who is considering upgrading to LED. (Posted on 6/2/14)

    The dull bulbs in my map light on my 98 integra wasn't cutting it anymore. I am also tired of grabbing the flashlight out of the glove box, every time I drop something on the floor. I replaced them with the cool white LEDs and what a big difference it made. Not only can I see the floor without a flashlight, but I can also see between the front seats and hump. Wow, it looks like I need to vacuum under there now (sad) :( (Posted on 5/18/14)
