Govee COB Strip Light 2 Pro Bright Specs & Cut Limit
The Govee COB Strip Light 2 Pro is a high-density LED strip with a brightness of 120 lumens per meter and a maximum cut interval of every 2.5 centimeters (about 1 inch), meaning you can cut it at any marked point without losing function of the remaining segments. This article explains the exact brightness specifications, the cutting rules, and what they mean for your installation.
Brightness Specifications
The COB (Chip-on-Board) design places 420 LEDs per meter, which produces a continuous, dot-free line of light. The rated brightness is 120 lumens per meter, roughly equivalent to a 10-watt incandescent bulb per meter of strip. For comparison, a standard 5050 LED strip with 60 LEDs per meter typically outputs 400-600 lumens per meter, but it has visible individual dots and a narrower beam. The COB strip’s advantage is uniformity, not raw output. In practice, 120 lm/m is bright enough for accent lighting, under-cabinet task lighting, or a TV backlight, but it will not replace a main ceiling light. The color temperature range is 2700K to 6500K, and the strip covers 100% of the sRGB color gamut, so colors appear vivid without dark spots.
Cut Limit and Markings
The strip has cut marks every 2.5 centimeters (0.98 inches). You can cut at any of these marks, and the remaining strip will still work normally. The cut line is a copper pad with a scissors icon. Do not cut anywhere else, as you will sever the internal circuit traces. Each cut segment retains its full functionality, including color control and brightness dimming. The minimum usable length is one segment (2.5 cm), but in practice you would use longer runs. The strip comes in a 5-meter roll, and you can cut it to any multiple of 2.5 cm. If you need a length that is not a multiple, you must cut to the nearest shorter mark and leave the extra unlit.
How Cutting Works
The strip uses a 4-layer flexible PCB with copper traces running the entire length. At each cut mark, the traces are exposed so that a clean cut separates the circuit cleanly. After cutting, you can either use the strip as-is (if it ends at a connector) or solder wires to the copper pads. The connector that comes with the kit is designed for the factory end; if you cut the strip, you need to use a solderless connector or solder directly. The strip operates at 24V DC, so you must maintain correct polarity when reconnecting. The cut segments do not have any special sealing; if you cut, the exposed end is not waterproof, so keep it away from moisture.
Power and Brightness Relationship
The strip draws 24 watts per meter at full brightness (1 amp per meter at 24V). If you cut the strip shorter, the total power consumption drops proportionally. For example, a 2-meter length draws 48W, and a 1-meter length draws 24W. The included power supply is rated for the full 5-meter length (120W), so cutting shorter does not require a different supply. However, if you extend the strip beyond 5 meters, you will need a higher-wattage supply and possibly a signal amplifier. The brightness is controlled by PWM (pulse-width modulation) at a high frequency, so you do not see flicker in videos or with fast eye movement. Dimming to 1% is possible without color shift.
Common Mistakes When Cutting
A frequent error is cutting at the wrong point, thinking any line is a cut line. Only the copper pad with the scissors icon is safe. Another mistake is cutting too close to the connector, leaving no room for a new connector. Always leave at least 1 cm of strip beyond the cut mark if you plan to attach a connector. Also, do not bend the strip sharply at the cut point; the copper traces can crack. If you solder, use a low-temperature iron and avoid bridging adjacent pads. Finally, remember that the strip is not rated for outdoor use unless you add a silicone sleeve; the cut end is especially vulnerable.
Comparison with Other Govee Strips
Compared to the standard Govee RGBIC strip (non-COB), the COB 2 Pro has a higher LED density (420 vs 60 per meter) and a uniform light line, but lower peak brightness per meter (120 vs 300+ lm/m for RGBIC). The RGBIC strip has individually addressable segments of about 10 cm, while the COB 2 Pro has 10 addressable zones per meter (each zone is 10 cm). For accent lighting where you want a seamless glow, the COB is better; for vibrant, punchy colors with visible effects, the RGBIC is brighter. The COB 2 Pro also supports Matter, which allows integration with Apple Home, Google Home, and Alexa without a separate hub.
Installation and Placement Tips
When planning your layout, measure the exact length you need and cut accordingly. The strip has an adhesive backing, but for a permanent install, use the included mounting clips. For corners, you can bend the strip at a 90-degree angle (it is flexible), but do not fold it flat. If you need to turn a sharp corner, cut at the mark and use a corner connector (sold separately). For under-cabinet lighting, mount the strip facing down, about 2 cm from the front edge, to illuminate the counter without glare. For TV backlighting, mount it on the back edge, facing the wall, and use the camera sync feature if you have the kit with a camera. The strip’s color temperature can be set to match your ambient lighting, which reduces eye strain.
Frequently Asked Questions
Can I cut the Govee COB Strip Light 2 Pro anywhere? No, only at the marked cut points every 2.5 cm. Cutting elsewhere will damage the circuit.
Will the strip still work after cutting? Yes, the remaining strip functions normally, but the cut end is not sealed and may be less durable.
What is the actual brightness in lumens? 120 lumens per meter, which is about 12 lumens per foot. For a 2-meter strip, that’s 240 lumens.
Can I extend the strip after cutting? Yes, you can use a solderless connector or solder wires to join two segments, but you must maintain polarity and not exceed the power supply’s wattage.
Is the strip waterproof? No, the strip has an IP30 rating (not waterproof). The cut end is even more vulnerable, so keep it dry.
Does cutting affect color accuracy? No, each segment retains full color control. The addressable zones are 10 cm, so cutting at a 2.5 cm mark may split a zone, but the zone will still show the same color across the cut.
