When sourcing LED strips from China, quality directly determines lifespan and performance. LED strips are everywhere — homes, hotels, offices — but not all are created equal. Here are 6 practical ways to evaluate LED quality before you place an order.
6 Ways to Evaluate LED Strip Quality
1. LED Binning
Consistent color temperature and voltage binning across every order ensures uniform color and stable performance. If bins vary between batches, you'll see visible color differences between strips.
Key point: Ask for bin consistency guarantees from your supplier.
2. Color Rendering Index (CRI)
CRI ranges from 60 to 90+. Higher CRI means more accurate, natural color reproduction. CRI>80 is standard for most applications; CRI>90 is needed for color-critical environments.
Key point: CRI>80 = good, CRI>90+ = excellent.
3. Brightness (Lumen Output)
At the same voltage, current, and wattage, higher brightness indicates better LED chip efficiency and quality. Compare lumens per watt (lm/W) across samples.
Key point: Higher lm/W = more efficient = lower energy cost.
4. Packaging Glue Material
LED chips are encapsulated with either epoxy resin or silicone. Under the same conditions (30°C, 1000 hours): epoxy resin loses 70% brightness, while premium silicone loses only 6%. Epoxy has poor heat conduction, accelerating light decay.
Key point: Always choose silicone-encapsulated LEDs for long-life applications.
5. Chip Brand & Size
Top brands include Nichia, Cree, BridgeLux, and Epistar. More reputable brands deliver better quality and consistency. Larger chip sizes (e.g., 14mil vs 10mil) also provide better performance and heat dissipation.
Key point: Verify chip brand and size in your supplier's specifications.
6. Working Temperature
Lower operating temperature = longer LED lifespan. At 30°C ambient, LED junction temperature stays below 45°C — ideal. But when 100 LEDs are packed at 11.4mm pitch, heat builds up and junction temperature can exceed 60°C, causing rapid light decay.
Key point: Ensure adequate heat sinking and proper LED spacing.
Epoxy vs Silicone: The 1000-Hour Test

brightness lost after 1000h at 30°C
Premium Silicone

Just finished the guangzhou lighting fair a couple of days, the customers were attracted by our products ranges.
and we just focus on led floodlight, led high bay, led projection lamp, led panels.
I’m not sure if you are interested in it. Pls find attached our whole range of products,
pls confirm me back if you want to know more about the products information.
Appreciated your prompt feedback.
Hello Cheers,let me know which item do you interesting ,we will send you our factory price list.
Here is new kinds of LED strips that perfect for growing in both soil and hydroponic mediums.
Blue (wavelength: 455-465nm): is good for photosynthesis; and help to induce Chlorophyll and Carotenoid, which are necessary for healthy leaves.
Red (wavelength:660-665nm) : is the peak wavelength for photosynthesis and photoperiodism. Red light is best for blooming and fruits.
What kind of plants you can grow with our LED Grow lights?
All kinds of flower plants : medical marijuana, cannabis, tomatoes, chilli , eggplant , Rose ect.
All kinds of greens : herbs and leafy vegetables, lettuce , bok choy ect .
Also suitable for Indoor garden or indoor potted landscape.
we can customize LED grow light for you based upon your request, so feel free to contact us if you want to customize, we will try our best to help you.
Hi dear , let me know more about your product detail. send us mail.
