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.
