SEALIGHT L2S H11/H9/H8 LED Bulbs review: 3.6/5 from the spec sheet
Fan-cooled H11/H9/H8 LED pair with a built-in driver, IP68 housing and 6500K output; the brand's own spec sheet lists 34,000 lm and 90 W per pair.
Fits: H11/H9/H8 sockets; 1:1 size; check for CAN-bus flicker on European makes

Score is calculated from the manufacturer's published specifications. BaniCar has not handled this unit. Specs and availability change — verify on the listing.
Safety note: Many LED retrofit bulbs are sold for off-road use only and are not DOT-compliant in halogen housings. Check federal and state law before installing on a road vehicle. We quote only what the manufacturer states.
Verdict
A reasonably priced fan-cooled H11 pair from a brand that at least publishes a spec table, with the caveat that its Amazon lumen claim is double its own sheet. Like every bulb in this category it is an off-road or fog-light part under federal rules, not a street-legal headlight upgrade.
Pros & cons
Pros
- Brand website publishes a spec table (34,000 lm, 90 W, IP68)
- Built-in driver — nothing to tuck behind the housing
- Lowest list price among the bulbs here with a brand page
- Non-polar plug, 1:1 footprint
Cons
- Not DOT/FMVSS 108 compliant for headlamp use; the manufacturer itself lists it for off-road, powersports or fog use
- Manufacturer figures conflict: 34,000 vs 70,000 lm, 14,000 vs 25,000 RPM, 1 vs 2 years warranty
- Fan-cooled design — more moving parts than a fanless bulb
- Some vehicles need an extra CAN-bus decoder
Best for
- Off-road and trail rigs with H11 housings
- Fog-light upgrades where allowed
- Buyers who want a brand page to cite

Frequently asked questions
Is this street legal?
Not as a headlight on public roads, as far as the published record shows. The manufacturer makes no DOT or FMVSS 108 compliance claim for this bulb, and NHTSA has forced recalls of aftermarket LED bulbs sold as halogen replacements because they exceeded the standard's luminous-flux limits. The Amazon listing files it under off-road, powersports, or fog use. Treat it as an off-road or show-use part and check your state's law before putting it in a headlamp housing.
Why do the lumen numbers differ?
SEALIGHT's own spec table lists 34,000 lm per pair while its Amazon listing says 70,000 lm. Neither is a lab-measured figure; use the lower one and compare wattage (90 W per pair) instead.
Will it flicker on my car?
SEALIGHT says 99% of vehicles run error-free and that some sensitive models need a CAN-bus decoder. European makes are the usual culprits — if your dash throws a bulb-out warning, you'll need the decoder.
