5 High Power LED

I have a base mazda 3 and don't see any feasible options for installing DRL's or Fogs.
Has anyone installed something like this? http://cgi.ebay.com/ebaymotors/5-LED...item27be57483a

I'm curious to know if someone has had any experience with such a product.

Re: 5 High Power LED

I haven't installed a kit like that, but I am in the process of designing and fabricating my own high powered LED system. First iteration will just be some DRL's but later on I intend to build a higher power system that could function as fogs. It will be a few weeks before I am able to post any progress on that project though as I still have 2-3 other things to finish up first.

Re: 5 High Power LED

How powerful are they? Have you done any testing?

Re: 5 High Power LED

It all depends on what kind of emitters I can get through my friends LED company. The first set of DRL's will probably only be a few hundred lumens per assembly. Eventually when I get around to making the high power system it will probably be 800-1200 lumens per assembly on the first gen (to save on the cost of emitters and make sure I have the design right). Though after that it would be trivial to up the power output to 3000+ lumens per assembly (granted it would cost a stupid amount of money for the emitters).

I'll be sure to keep you posted on progress as I build my first iteration in the next few weeks.

Re: 5 High Power LED

Any updates? I am looking for replacement fog lights that will match my factory HID's 4700K I think and I want the most lumens available so I will not lose much output from the OEM halogens.

Re: 5 High Power LED

Are you trying to replace your fog bulb to LED bulb? then, you will lose lots of output with LED bulbs. If you concern about useful"output" LED bulb should not for your choice.

BTW, for LED white, higher the color temperature gets more lumen.

For now, only way you can make useful LED lighting( for fog lamp replacement) is to make proper optics with at least about over 15W output power per lighting.
multi emitter setting is much easier to accomplish useful level output.

something like multi numbers of XP-G will be good start for DRL level output, for fog, maybe XM-L, SST-50 or SST-90 emitters
Thermal management and reliable constant current driver design will be essential though.

from my experience, for DRL use, about 5-7W total output level will be fair. For fog, you should look for around 15W minimum with high focus on vertical axis, 30+ degree for horizontal axis type optics.

Unfortunately, non of commercially available LED bulb can achieve that so far. Almost all of those LED bulb use cluster design which can't simulate lighting point to achieve proper focus by reflector.

Re: 5 High Power LED

After a lot of trial and error I found these. http://www.amazon.com/gp/product/B005JFQ2RG They fit the stock housing and fit behind the reflector. They are fairly blue ~6500 but look better than the OEM halogens. The output is pointless as the new 3's fogs add little to no output to the bi-xenons.

Just my 2 cents...
