Choose the Right LED Diffuser Tube for Your Fixture
Start with the part that must fit your product, then select the appearance and cut length. This keeps the finished cover consistent with your housing, lighting effect and assembly process.
01
Match the cross-section
Use the 55 mm profile when it fits your housing. For a new fixture or replacement cover, send the mating dimensions so the extruded diffuser can be made around the actual assembly. If you're working from an existing part rather than a drawing, this guide on how to identify a diffuser profile by its cross-section walks through reading the shape, lip and fit before you request a quote.
02
Choose the light appearance
Clear keeps the light source more visible, semi-clear gives a balanced translucent look, and opal creates a more concealed appearance. Select the option that matches the finished fixture. For the transmission trade-offs behind each option, see our breakdown of how LED diffuser cover types affect light transmission.
03
Set the finished length
Order pieces from 0.5 m to 5 m to suit your production and installation plan. Defining the cut length early also helps us recommend carton or wooden-box packing.

Why Polycarbonate Diffuser Tubes Suit Demanding Lighting
Polycarbonate combines impact strength, optical transparency and a wide usable temperature range. It is a practical material for covers that need to protect the light source without adding a fragile glass component. Browse our full range of extruded lighting polycarbonate profiles for other stock sections and finishes.
Resists handling impact
The strong impact performance of PC helps the cover tolerate contact during assembly, transport and installation. That reduces the risk of changing to a more fragile lens material in applications exposed to regular handling.
Handles temperature changes
This diffuser profile is suitable for a working range from −40°C to 120°C. Share the real operating conditions with your inquiry so we can align the proposed material grade with the fixture environment.
Supports outdoor and electrical uses
Weather resistance and electrical-insulation capability make the extruded cover relevant to LED lighting, electronic components and construction applications where material stability matters.
Match the Plastic Diffuser Profile to Your Lighting Design
The right finish depends on how much of the LED source should remain visible in the completed product. Choose the visual result first, then confirm it against your fixture.
Clear
Keep a transparent appearance
Use clear material when the design calls for strong transparency and the LED source can remain visible through the lighting cover.
Semi-clear
Balance visibility and diffusion
A semi-clear lens gives the profile a translucent appearance without fully hiding the light source, making it a useful middle option for visual evaluation.
Opal
Create a more concealed look
Choose opal when the fixture needs a more diffused appearance and reduced visibility of the components behind the cover.
PC or PVC
Select the material for the application
Polycarbonate is available for impact, temperature and self-extinguishing requirements; PVC is also offered when it better matches the project specification. See our PMMA vs polycarbonate LED diffuser material comparison for how the two materials compare on heat, impact and flame rating.
OEM LED Diffuser Tubes for Lighting and Component Projects
Standard and custom profiles can be specified for lighting covers, protective lenses and other extruded components. The 55 mm format provides a ready starting point, while custom sizing supports products with their own housing geometry.
LED lighting covers and lenses
Cover linear LEDs with a continuous extruded profile that protects the source and gives the finished fixture the selected optical appearance. Our PC LED light diffuser profile covers this application with transmission, impact and flame-rating options in one part.
Electronic components
Use the material's electrical-insulation capability and selectable profile size when the component needs a shaped plastic cover rather than a flat sheet.
Construction applications
Weather resistance and lengths up to 5 m support evaluation for long protective or finishing profiles used in construction-related products.
Build a Custom Dachang LED Diffuser Tube Around Your Product
Dachang designs, produces and delivers custom plastic extrusions. Start from the 55 mm profile or send the dimensions required by your housing, then define the material, finish, length and packing for production.
Share the required shape
Send the cross-section, mating dimensions or current part details so the custom diffuser profile can be reviewed against your product.
01
Select material and finish
Confirm the plastic material and optical appearance required for the finished cover.
02
Set length and quantity
Confirm the finished piece length and order quantity so pricing and packing can be prepared together.
03
Confirm the order basis
Align the quotation, dimensions, appearance and packing requirements before the custom extrusion moves into production.
04
Ask Dachang to quote your OEM diffuser profile
One message with the drawing, material, finish, length and quantity is enough to start.
Select a Flame Retardant Polycarbonate Grade for Your Application
Some available grades meet UL94 V-0, V-1, V-2, HB, 5VA or 5VB classifications. Tell us which classification your product requires so the material can be confirmed for that specification.
Match the grade before ordering
Flame classification depends on the selected material grade; it should not be assumed from the finish or profile shape. Include the required UL94 level with your drawing and operating conditions when you request the quote.
Pack Bulk LED Diffuser Tube Orders to Protect Long Profiles
Choose carton or wooden-box packing after the piece length and quantity are fixed. This keeps the packing method aligned with the size of the finished extrusions and your handling requirements.
Carton packing
Cartons are available for orders that suit this packing format. Add any shipping marks and labeling requirements to the inquiry.
Wooden-box packing
Wooden boxes can be selected for long profiles or when the delivery plan calls for a more rigid outer package.
Get MOQ and Lead Time for Your Custom Extrusion
MOQ and production timing are confirmed with the quotation because standard and custom profiles do not follow the same order conditions. Send the configuration, quantity, destination and required delivery date for project-specific terms.
What helps us quote faster
Include the profile size or drawing, material, finish, cut length, total quantity, packing choice and delivery location. Complete requirements reduce follow-up questions and help Dachang return a more useful factory-direct quotation.
