What we manufacture
Each product page states voltage, power per metre, cut length, sealing and lead time up front, so you can tell in ten seconds whether it fits the project.
COB LED Strip
A COB LED strip is a flexible linear light source in which bare LED dies are bonded directly onto the FPC and sealed under one continuous phosphor layer, so the light is dot-free instead of showing individual emitters. HFY LED builds COB strips at 320, 480 and 504 chips per metre on 24 V, delivering 8–15 W/m at CRI 90–95 with SDCM ≤ 3 colour consistency, in reels from 5 m to 50 m and sealing from IP20 to IP68..
Specifications and process
SMD LED Strip
An SMD LED strip carries packaged surface-mount LEDs on a flexible PCB at a fixed pitch, which makes it the lowest cost per lumen option for volume lighting. HFY LED produces 2835, 5050 and 5630 strips from 60 to 240 LEDs per metre on 12 V or 24 V, at 100–190 lm/W and CRI 80–90, with reels from 5 m and typical production lead times of 15–20 working days..
Specifications and process
Silicone Neon Flex
Silicone neon flex is a flexible linear light in a solid silicone profile that diffuses the LED source into an even, continuous line while sealing the electronics to IP67. HFY LED extrudes neon flex in 6×12 mm, 8×16 mm and 10×20 mm profiles on 12 V or 24 V, at 5–12 W/m, in top-bend and side-bend versions, from 2700 K to 6500 K plus RGB and RGBW..
Specifications and process
RGB & Pixel LED Strip
An addressable pixel strip contains an IC at every LED or every three LEDs, so each pixel can be set to an individual colour and brightness from a controller. HFY LED supplies RGB, RGBW and addressable strips on WS2812B, WS2811 and SPI 12 V and 24 V platforms, from 60 to 144 pixels per metre, with custom pixel mapping, lead frames and IP67 sealing for outdoor media facades..
Specifications and process
Lightbox & Side-Emitting Strip
A lightbox LED strip is a side-emitting or zigzag-arranged strip that throws light sideways into the acrylic face of a sign, producing even brightness without the hot spots of a direct-view strip. HFY LED supplies side-view 3014 and 335 strips and zigzag backlight strips at 0.6–1.5 W per module on 12 V or 24 V, sized to box depths from 60 mm to 300 mm, with IP65 sealing for outdoor signs..
Specifications and process
S-Type Bendable LED Strip
An S-type bendable LED strip uses a zigzag FPC that folds in every direction, so the strip follows loops, curves and 3D letter shapes that a straight strip cannot. HFY LED builds S-type strip at 60 LEDs/m on 12 V (7.2 W/m) with 5050 packages, and Z-shape 3535 WS2815 pixel versions at 90 LEDs/m for illuminated letters..
Specifications and processOne process chain, one bin record
Die bonding, SMT assembly, sealing and photometric testing run under the same quality system, so a reel does not lose its colour record when it moves between operations.

Sectors we supply — and what each one actually specifies
Architectural Lighting
Architectural lighting specifications turn on colour consistency, dimming behaviour and serviceability rather than on price per metre. HFY LED supplies COB and high-CRI SMD strips at SDCM ≤ 3 with CRI 90–95, in 24 V runs up to 10 m from one feed and 50 m reels, and holds a bin record per project so replacement strip matches the installed installation years later..
Requirements and partsSignage & Lightboxes
Signage lighting is judged on uniformity and service life, because a sign that goes patchy is a visible brand problem. HFY LED supplies side-emitting and zigzag strips plus backlight modules for boxes from 60 mm to 300 mm deep, validates each layout in a physical test box to ≥ 85% edge-to-centre uniformity, and seals outdoor builds to IP65 with a 30-minute spray test..
Requirements and partsRetail & Display
Retail lighting has to render merchandise accurately and disappear into the fixture. HFY LED supplies CRI 95 COB strip at SDCM ≤ 2 for shelving and display cases, in 8 mm and 10 mm widths that fit inside 15 mm aluminium profiles, with 0–100% dimming through DALI, 0–10 V or phase-cut drivers..
Requirements and partsHospitality & Leisure
Hospitality projects need warm, dimmable light that survives cleaning chemicals and stays repairable for a decade. HFY LED supplies CRI 95 COB strip in 2700 K and 2400 K, warm-dim drivers that shift to 1800 K at low output, and IP67 neon flex for spa and pool areas, with the bin record held per project so refurbishment reels match the original..
Requirements and partsProjects where colour control, not price, was the risk

Read case studyWhat the production lines actually look like
Buyers get burned by suppliers whose website shows a showroom and whose workshop is two tired machines. So the facility pages show the die bonder, the SMT hall, the extrusion line and the laboratory, with model numbers and tolerances you can check against your own requirement.

What is the minimum order quantity for LED strip?
Stocked configurations ship from 1–10 metres for evaluation and from 500 metres at volume pricing, because the phosphor batch and stencil setup are fixed costs above that point. Samples ship in 3–5 working days, and sample cost is credited against the first production order.
How fast can you deliver to Europe or North America?
Stocked strip ships in 3–5 working days; production runs take 10–18 working days after sample approval. Air freight adds 4–6 days door to door, and sea freight 28–35 days for volume orders above 500 kg.
Can you guarantee a colour match between production runs?
Within a bin record, yes. Every reel is measured on a spectroradiometer and binned to SDCM ≤ 3, and we hold bin records for five years. For multi-phase projects above 800 m we reserve one die bin for the whole programme, which is the only way to keep phases six months apart identical.
Do you supply drivers and profiles as well as strip?
Drivers, yes — 12 V and 24 V constant voltage from 30 W to 400 W, dimmable by DALI, 0–10 V or phase-cut. Aluminium profiles are supplied through partners; we quote the profile matching the strip width and state the temperature rise it gives so the life calculation is honest.
What documentation comes with a shipment?
A lot certificate with bin code, flux, forward voltage and burn-in record, plus CE, RoHS and REACH declarations. LM-79 reports, LM-80 data and TM-21 projections are available on request, and IP67 assemblies ship with a pressure-test record.
Can I visit the factory or audit before ordering?
Yes. Audits are arranged within two weeks and cover the COB line, SMT hall, silicone extrusion, the photometric laboratory and packing. Remote video audits are available if travel is impractical, and we would rather host a first order than quote blind.
