Product Specification

HuanYu Dream Plant Blue 2835 450nm Blue SMD LED Chip 5-7LM for Seedling Stage LED Grow Light Panel

• 450nm blue plant growth LED chip, 2835 package 0.2W, PPF>3.0 μmol/s/W, precisely matched to chlorophyll B and carotenoid absorption peaks, ideal for seedling-stage supplemental lighting and hydroponic leafy green grow panels
• PPF>3.0 μmol/s/W (industry peers typically 2.0-2.5), 5-7LM luminous flux, driving blue-band photosynthesis and photomorphogenesis — prevents leggy growth, promotes compact structure, thicker leaves, and stronger roots; results vary with photoperiod and plant spacing
• 2.8×3.5mm 2835 package, dominant wavelength 450nm (±5nm), 0.2W rated power, 60mA drive current, 2.8-3.4V forward voltage, PPF>3.0 μmol/s/W, 5-7LM
• Designed for vertical farm seedling racks, hydroponic leafy green panels, and home grow light makers; during seedling stage (4-8 true leaves) blue-dominant lighting keeps seedlings short and sturdy, improving transplant survival; pairs with 660nm red at 1:2-1:4 ratios for full-cycle grow solutions

FAQ

Q1. Can I have a sample order for led light?

A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.

Q2. What about the lead time?

A:Sample needs 1-3 days, mass production time needs 3-7 days according to the order quantity .

Q3. Do you have any MOQ limit for led light order?What's the Payment way ?

A: MOQ is 100pcs for each model. We accept T/T Paypal and Western Union three ways payment.

Q4. How do you ship the goods and how long does it take to arrive?

A: We usually ship by DHL, UPS, FedEx or TNT. It usually takes 2-5 days to arrive. Airline and sea shipping also optional.

Q5. How to proceed an order for led light?

A: Firstly let us know your requirements or application. Secondly We quote according to your requirements or our suggestions.Thirdly customer confirms the samples and places

Q6. Is it OK to print my logo on led light product?

A: Yes. Please inform us formally before our production and confirm the design firstly based on our sample.

Q7: Do you offer guarantee for the products?

A: Yes, we offer 3 years warranty to our products.

Q8:Why is the lumen output only 5-7LM?

A: Lumen measures human-visible brightness, but plants respond to PAR  (photosynthetic photon flux). Blue light has inherently lower luminous efficacy than white — what matters for growers is PPF, and ours delivers  >3.0 μmol/s/W, which is above industry average for 0.2W blue chips.    Judge us by PPF, not lumens.
