Re: Any decent LED retrofits for H3 out there?


 


Regarding your question about suitable H3 LED options: Porsche specified 55-watt H3 halogen bulbs for the fog and auxiliary driving light locations. 55-watts (halogen) is the equivalent?of 1240 lumens. So when looking for LED alternatives, you would want similar or more lumens in order for them to be effective. As pointed?out, there are not many H3 LED bulbs that offer comparable lumens and will fit in the factory location. Higher-lumen H3 LEDs often come with large power?supplies and heat syncs that require modification to the light assemblies.

I have experimented with several H3 options, including the Woodypeck variant. They all do not produce enough lumens to be effective to see with. In my latest experiment, I have been using bulbs in both the Fog and Aux locations. They have 1600 lumens per bulb, which is slightly brighter than a 55-watt halogen bulb. I can actually tell when they are on, and the illumination seems comparable to the halogen.?

They also come in a , which i am trying for my fog location, which I also really like.

These bulbs will fit into the fog light assembly. The retaining clips do require some finessing around the base cooling fins. Also, I had to split the casing that houses both leads so I could match them into their respective receptacles. I used a sharp, thin blade (ie, box cutter). It's obvious when you have them in your hands with the fog lights apart.??

Everyone will have their own rationalization to use or not use LED bulbs. For me, I am drawn to the low power utilization if I can match the lumen output and make everything look good. Replacement LED's for the headlights (H4 or 9004) can be found with more than double the lumen output of the standard halogen bulbs with a fraction of the amp draw. So I started there and decided to try and color match 6000k the rest of the front-facing lights.

I dont expect any H3 ever to work in our shallow housings.? Ever.? And be better.? Ever. ?

How long ago did you try Woodpeck's kit?? I just looked it up and noticed that they're advertising the current offering as being "new for 2022."? (Of course, they're also making the contradictory claims of only 450 lumens output and "equivalent to 80w Halogen bulb" [which would be >2000 lumens], so I probably shouldn't hold my breath.)
