GX-ULTRA Series 40000LM 240W Brightest LED Headlight Bulbs 6500K Cool White

Auxbeam GX-ULTRA Series LED headlight bulbs are the brightest in the lineup, delivering 40,000LM / 240W per pair in 6500K cool white — up to 950% brighter than halogen. Each bulb packs 12 upgraded 7545 CSP 77-mil LED chips (24 on dual-beam sockets) behind a 1:1 factory beam position design, cooled by a 4.0mm dual copper tube and a 20,000RPM turbofan for a 55,000-hour lifespan. CAN-BUS ready smart IC drivers work with about 99% of vehicle computers, and the near 1:1 halogen size installs plug and play in about 10 minutes. Available for H11/H9/H8, 9005/HB3/H10, 9006/HB4, 9012/HIR2, H7 and H4 sockets as 2-bulb kits or 4-bulb combo kits — engineered for cars and SUVs (pickup truck owners, see the fitment note below).

UPGRADED FEATURES

950% BREAKTHROUGH BRIGHTNESS

• 240W and 40,000 lumens per set — the brightest output in the industry — driven by the largest 7545 CSP 77-mil LED chips: 12 chips per bulb on single-beam sockets and 24 chips on Hi/Lo dual-beam sockets, producing about 10 times the light of a stock halogen bulb for a safer, more comfortable journey.
• Power note: because of the high power draw, vehicles with old or small headlight fuses should replace the fuse before installation — one rated 10A or above, and no more than 20A — to avoid blowing it.
  

SUPER FOCUSED BEAM PATTERN

• Featuring a 1:1 factory beam position design with ultra-thin chip spacing, these LED bulbs perfectly reflect a super-focused beam pattern with 360° stable full lighting. 

4X HEAT CONDUCTION SPEED

• An all-in-one aluminum body, a bold 4.0mm dual copper tube and a 20,000RPM super-speed cooling fan work together to deliver 4 times faster heat conduction — pulling heat off the high-power chips fast enough to sustain peak output for the long haul.

GX ULTRA SERIES, NEW GX EVOLUTION

•  The new GX Evolution family matches different driving scenarios: the GX-ULTRA Series is the high-power, high-lumen flagship with super-focused output for maximum visibility; the GX Series (25,000LM / 120W) is the extremely bright best-seller for safe, reliable road lighting; and the GX Bi-Color Series switches between 6500K and 3000K dual-color for wider, farther illumination in any weather.

ALL-IN-ONE DESIGN & EASY INSTALLATION

• The same size as the original halogen bulb for higher compatibility — real plug and play, quick install in about 10 minutes. If the cooling fan is too large or too deep for the factory dust cover, simply replace it with a silicone dust cap.

99% VEHICLE COMPATIBILITY

• The upgraded smart IC driver is CAN-Bus ready and directly alleviates decoding issues, compatible with about 99% of vehicle computer systems without error. Some sensitive brands — Mercedes-Benz, BMW, Volvo, Dodge, Ford Fusion, Ford Focus, Ford Escape and similar — may flicker after installation; this is not a quality issue and is solved with CANBUS decoders or our LED decoding guide.
