Frequently Asked Questions (FAQs)
Lens diffused LED strip: Expert Q&A
Get expert answers on critical topics including 170° wide beam angle performance, shadowless illumination for ultra-thin light boxes, thermal management, IP waterproof ratings, and custom sizing for our Lens Diffused Backlight LED Strip. Built for commercial lighting contractors, brand store fit-out teams, and signage manufacturers, this Q&A helps you select the right backlight solution for your architectural, retail, and advertising projects.
01. What is a 2835 backlight LED strip used for?
It’s specifically designed for ultra-thin light boxes (3–5cm), advertising signage, stretch ceilings, retail display cabinets, and architectural cove lighting where uniform edge-to-edge illumination is required.
02. Why is a 170° beam angle important for backlight applications?
A 170° wide beam angle eliminates hot spots and dark zones inside a light box, allowing thinner installations (as slim as 3cm) while maintaining uniform brightness — standard 120° strips require deeper boxes to diffuse evenly.
03. What voltage and power options are available?
NPHIS offers DC 12V and DC 24V as standard, with DC 48V available on request. Power density is customizable from 5W/m up to 25W/m to match light-box depth and brightness needs.
04. Can the LED strip be cut to custom lengths?
Yes — the strip features a single-LED cuttable design, allowing you to cut every individual LED segment, far more flexible than typical strips that cut every 3–5 LEDs.
05.What color temperatures are available?
Six standard CCT options: 2700K, 3000K, 4000K, 5000K, 6500K, and 10000K, with custom CCT and Pantone color matching available via OEM service.
06. Is the back-lit bar waterproof?
Two IP ratings: IP20 (indoor light boxes — default) and IP67 (silicone-coated for outdoor signage / humid environments). IP68 PU coating available on request.
07. What certifications does NPHIS LED hold?
Standard CE and RoHS for all products; UL, ETL, and TÜV available on request for North American and EU markets. ISO-certified factory with LM80-tested chips.
08. What's the MOQ, sample policy, and lead time?
Free samples up to 10 meters; bulk MOQ starts at 500m; standard lead time 7–15 days, with express production available for urgent projects.
09. What warranty is provided?
A 3–5 year manufacturer warranty backed by LM80-certified chips, 2oz copper aluminum PCB, and full batch thermal aging tests before shipment.
10. How do I get samples, pricing, and technical support before placing a bulk order?
We have a structured B2B onboarding process:
- Sample Request — Submit your profile, color, and voltage requirements via our quote request form. Samples (1–5m) are available at cost price + shipping, credited against your first bulk order.
- Technical Consultation — Our engineering team reviews your project specs and recommends the optimal product configuration.
- Formal Quotation — Tiered pricing provided based on volume, with lead time confirmation.
- Pre-production Sample (PPS) — For custom/OEM orders, a PPS is approved before full production begins.
- Bulk Production & QC — Full production with in-line QC and pre-shipment inspection report available.
