When buying LED light strips, do the dazzling parameters and price differences make you feel overwhelmed? Don't worry, master the following key points, quickly develop a keen eye, and easily avoid inferior products:

LED Light Strip Buying Guide: How to quickly distinguish between good and bad? 5 tips to avoid pitfalls! 1

1. Look at the chip and package: the foundation of quality
· Chip brand: Prefer well-known brand chips such as Cree, Bridgelux, and Epistar, which have stable performance and low light decay.
· Packaging process: Observe whether the lamp beads (such as the common 2835 and 5050 models) are full and evenly arranged, and whether the solder joints are smooth and firm. Inferior lamp beads are prone to dead lights and dark areas.

2. Measure brightness and light efficiency: the key to efficiency
· Brightness (lumen value): Don't just look at the power! Under the same power, higher brightness usually means better light efficiency and more energy saving. Ask suppliers to provide measured lumen values.
· Luminous efficiency (lm/W): Measures the efficiency of converting electrical energy into light energy. The luminous efficiency of high-quality light strips is 120lm/W or even higher. High efficiency means long-term power saving.

3. Check color rendering and consistency: visual experience
· Color rendering index (Ra/CRI): Selecting a light strip with Ra≥90 can highly restore the true color of objects, especially suitable for home and commercial display scenes.
· Color consistency: The color of the lamp beads should be highly consistent between the same roll of light strips and different batches to avoid color difference.

4. Check the circuit board and process: stability guarantee
· Substrate material: Prefer high-quality double-sided fiberglass board (FR4) with sufficient copper thickness (such as 2oz) and uniform copper coating. Poor-quality substrates are prone to heat deformation and copper foil breakage.
· Welding process: The solder joints should be round and full, without false solder joints. The position of the patch components is accurate and the overall workmanship is fine.

5. Choose power supply and accessories: safe and durable
· Matching power supply: Be sure to choose a dedicated LED power supply with sufficient power, high efficiency (≥85%) and certification (such as UL, CE). Poor quality power supply is the culprit of failure and short circuit.
· Quality of auxiliary materials: Pay attention to the waterproof level (such as IP65/IP67), the flexibility and weather resistance of the rubber sleeve/glue. Silicone sleeves are more durable and environmentally friendly than PVC.

Professional advice:
For engineering companies, designers and bulk purchasing users, it is crucial to choose a source manufacturer with independent research and development capabilities like Shenzhen Jomo Lighting Technology. We strictly select first-line brand chips and raw materials, implement production processes that are higher than industry standards, provide precise optical parameters and complete certification support, and ensure that every meter of light strips are of consistent quality.

Through these five essential judgments, you can quickly filter out inferior LED light strips, lock in truly cost-effective and long-life lighting solutions, and lay a solid foundation for project success.
