Frequently Asked Questions
Is the 11,000-lumen figure for one bulb?
The published rating for SKU A1001 is 11,000 lumens per set. Keep that unit with the number when comparing products; it is not a measurement of light delivered to a particular point on the road.
What light colour is this H11 product?
This exact listing specifies 6500K white light. Match the SKU and product generation when replacing an existing bulb; another Alpha Series bulb can have a different specification.
Can I choose these H11 LEDs only by my truck model?
Check the exact lamp position and bulb marking first. A Freightliner Cascadia, Peterbilt, Kenworth or Volvo model name can cover different headlight equipment, including replacement housings. The installed lamp must use the matching H11 bulb and provide suitable clearance.
What voltage range is listed for A1001?
This exact product lists a 9–32V DC input range. Check the actual lighting-circuit supply and connector against that range.
Does an LED bulb replace a complete factory LED headlight?
This is a replacement-bulb product for a compatible serviceable lamp. A complete factory LED headlight can use different integrated electronics and light sources; a model name or similar exterior housing is not a bulb-fitment check.
Will built-in electronics prevent every warning or flicker?
Do not assume a universal result. Check the installed bulb type, connections and lighting circuit. Some applications require an appropriate additional module; diagnose the cause before choosing electrical accessories.
What should I check around the H11 cooling system?
This product lists: copper pcb, liquid-filled thermal tubes and an internal cooling fan. Check the space available behind the bulb and the way the original dust cap closes. Keep the cooling path and mounting arrangement consistent with the supplied installation instructions.
What warranty applies to this Alpha Series bulb?
The current product carries a lifetime limited warranty. The existing terms and exclusions for the purchased product apply; a warranty does not make an incompatible housing or electrical supply suitable.
