CHANZON 100W Far Red LED Chip 730nm Plant Grow Light - High Power

In this review of the CHANZON 100W Far Red LED Chip the bottom line is simple: this module is for hobby growers and DIY lamp builders who need a high-brightness 730nm far red emitter with robust construction. The reviewer found the integrated COB design, double golden wire and copper frame deliver concentrated output and sensible durability for the price, while the clear requirement for a heat sink and a constant-current driver is the one operational detail builders must respect.

Key Features

• 100W output: Delivers a high-power far red emitter suitable for supplemental spectrum in flowering or photomorphogenesis experiments.
• 730nm far red: Produces a targeted wavelength useful for extending shade response and influencing flowering timing when paired with other LEDs.
• Integrated COB panel: The chip on board design and 45mil dies concentrate light and simplify mounting into custom fixtures.
• Robust construction: Double golden wire and copper frame improve thermal and electrical reliability compared with basic emitters.
• Wide beam angle: 120-140 degree emitting angle gives broad coverage from a single module for DIY arrays.
• Long lifespan: Rated for up to 50,000 hours when operated below 60C with a heat sink, offering long-term value.

Who It's For

This module is aimed at makers and small-scale growers who build or retrofit their own grow lamps and need a concentrated far red source. It works best for users who understand constant-current LED drivers and thermal management, because the chip requires a 3000mA input and proper heat sinking to reach rated life.

It is not a plug-and-play replacement for standard bulbs; casual buyers without experience designing LED systems or sourcing a matching driver and heat sink should look for finished fixtures instead. Also, those needing broad-spectrum solo lighting should combine this with other wavelength LEDs rather than rely on it alone.

Pros & Cons

Pros

• High brightness and focused far red output that integrates well into custom grow arrays.
• Solid build quality with copper frame and double golden wire for better durability.
• Wide emitting angle gives good coverage from a single emitter in DIY setups.
• Long rated lifespan when cooled correctly, offering good value for builders.

Cons

• Requires a constant-current driver (3000mA) and effective heat sink; not ready to run by itself.
• Heat dissipation can be mixed depending on user cooling solution, so additional thermal design is needed.

Specifications

Our Verdict

For DIY growers and lamp builders who can supply a 3000mA constant-current driver and a quality heat sink, the CHANZON 100W far red COB is a cost-effective, well-built way to add targeted 730nm output to a lighting array. It is good value when incorporated properly, but novices should be prepared to handle thermal and electrical integration.

Frequently Asked Questions

Does this chip need a special driver?
Yes. Use a constant-current LED driver rated for 3000mA and the specified voltage range to operate safely.

How should it be cooled?
Mount it to an appropriate heat sink and keep operating temperature below 60C (140F) for long life.

Can this be used alone as a full grow light?
No. It is a single-wavelength far red emitter best used as a supplement alongside other spectrum LEDs or in multi-emitter arrays.
