Fan Cooled Technology in a replacement bulb!  

(Sold as set of 2 Bulbs)


LumX has been pushing the boundaries of what is possible when it comes to external LED bulbs. While other manufacturers focus on headlight bulbs, we're trying to create extremely bright, efficient replacement bulbs for other applications. 


The LumX FC series is the latest example of this push. We packed 50 separate EMC LED chips onto this one bulb! This creates a staggering 2000 Lumens PER BULB! This would not be possible without an efficient cooling method. For this we designed, from what we've seen, to be one of the first reverse lights with a built-in electronic fan to cool the bulb! 


There are certain applications where our normal heat sink cooled reverse light set will not work. For those applications we've created the FC series! "Fan Cooled"


This creates an extremely universal bulb that will work on any application where the socket fits! 


Bulb plugs into a circuit base? ☑️

Vehicle have blind spot monitoring? ☑️

Long as its a 7440 base, this bulb will fit ☑️

Dieselleds; great product even better service!

We purchased replacement lights for our 1999 Ford F-350 Super Duty; the product is great from new led lights replacing the OEM headlight bulbs to the interior lights and the back up lights; the product has made a huge difference for safety and overall performance; however the service at Dieselleds is truly amazing; who knew they would truly read the comments with our order when we asked them to verify all the product would fit properly without any fitting opportunities; they actually checked and wrote back to advise they were changing an item out and upgraded it to be certain it was simply and worked perfect…thanks for the help and support Jim
