2015 Ford Fiesta ST Fog Light LEDs (pair)

FUNCTION

Fog Light LED bulbs are an excellent way to improve the appearance of your vehicle. From the factory, most vehicles come with halogen bulbs, which project in a yellowish light. By replacing them with LEDs, you can create a modern appearance with the cool white light of LEDs.

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

Please note: Fog Light LEDs are primarily for cosmetic upgrade. Some models may not provide an increase in output.

BULB DESIGN

HP48: This bulb is designed with 48 Epistar 3014 LED chips. Thanks to the cap on the top, the light from this High Power Bulb is shined backwards and away from the bulb, not straight out. This means the output is excellent, because it uses the vehicle’s housing completely, which then shines the light much more uniformly.

HP8:Four side-firing 1.5W-rated Osram LED chips, and one 1.5W-rated chip on top. The bulb is housed in a machined aluminum casing, which provides superior heat diffusion for long life.

XP80:Each of the four sides of this bulb contains three 5W-rated chips, and the top is fitted with four more, under a projector lens. This is the brightest self-contained automotive LED bulb on the market, and is housed in an aluminum casing with a textured finish for maximum heatsinking properties.

XML2: NEW!Two opposing genuine CREE XM-L2 chips, driven at high power by self-contained regulator unit, in an attractive cast-aluminum housing. Fully waterproof, non-polar, modular design.

Fitment.SMD, HP, and XP bulbs use an inject-molded terminal, with a full-size base connector, designed for exact replacement of your factory bulb.The XML2 bulb fits in the same way, but also requires an additional 2″ of clearance behind the bulb socket- see pictures.

Included in your order is TWO BULBS.

COLOR

These LEDs illuminate in a crisp, bright,cool whitehue. The XML2 is also available innatural white, pure white, and yellow.

BRIGHTNESS

Diode Dynamics offers several brightness options so you can choose what fits you best. These options are listed by the design and the lumen output of each bulb, compared to the factory bulb.

HP48: 265 lumens.Slightly lower brightness than factory.
HP8: 270 lumens.Slightly lower brightness than factory.
XP80: 510 lumens.Similar brightness to factory.
XML2:1410 lumens.Much brighter than factory. These are bright!

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.

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 CREE, Epistar, Cree, Osram, and Samsung.

While Diode Dynamics 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 bulbsexhibit 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.
