Question 1

What are the common applications for this COB LED strip light?

Accepted Answer

This 6704 COB LED strip light is widely used in decorative lighting, signage, advertising signs, exhibition booths, and residential architectural lighting projects due to its uniform light output.

Question 2

What is the maximum continuous run length for the 6704 COB LED strip?

Accepted Answer

The maximum recommended continuous run length for this 24V COB LED strip is 5 meters to ensure consistent brightness and prevent voltage drop issues across the entire strip.

Question 3

Is this COB LED strip dimmable and what kind of power supply does it require?

Accepted Answer

Yes, the 6704 COB LED strip is dimmable. It requires a compatible 24V constant voltage (CV) LED driver to function properly and allow for dimming control.

Question 4

Does this product meet any environmental or safety standards?

Accepted Answer

Yes, this COB LED strip light is designed to be free from harmful substances and is in compliance with the RoHS environmental standards, ensuring a safe and responsible lighting solution.

Question 5

Is a COB LED strip better than an SMD strip for dot-free lighting?

Accepted Answer

Yes for continuous linear light. A COB LED strip spreads phosphor over the whole surface, so there are no visible dots even without a deep diffuser, while a standard SMD strip needs 240 LEDs/m plus a frosted cover to get close. Choose SMD only when you need higher output per watt or RGB pixel control.

Question 6

What is the difference between RGB and RGBW LED strip lights?

Accepted Answer

An RGB LED strip mixes red, green and blue dies to produce colour, and its 'white' is a mix that always carries a colour cast. RGBW LED strip lights add a dedicated white die — 2700K to 6500K, Ra 90+ — so the same run can deliver usable architectural white and saturated colour scenes without a second channel of tape.

Question 7

Should I use a 12V or 24V RGB LED strip?

Accepted Answer

24V is the default for architectural work: at the same wattage it draws half the current of 12V, so a single feed covers 5–10 m without visible colour shift at the far end. 12V RGB LED strip is reserved for short cabinet, furniture and vehicle runs where the driver or controller is 12V-native.

Question 8

Can an RGB LED strip be dot-free?

Accepted Answer

Yes, if the LED pitch is tight enough for the three dies to blend before the light leaves the diffuser. DENO builds high-density RGB boards at 2.1–4.2 mm pitch, which removes both the dot pattern and the rainbow fringing typical of 60 LEDs/m colour tape in shallow profiles.

Question 9

Do you make an outdoor waterproof RGB LED strip?

Accepted Answer

Yes. RGB builds are available IP65 silicone-coated, IP67 sleeved and IP68 fully potted, plus DENO WAP™ conformal coating that stays clear and flexible instead of yellowing. Marine-grade variants add salt-spray resistant terminations for dock and yacht installations.

Question 10

How is an RGB LED strip controlled — DMX, DALI or a standard controller?

Accepted Answer

Common RGB tape is a 4-pin constant-voltage load, so it works with any PWM controller: standard RF/Wi-Fi controllers, 0–10V, DALI DT8 or DMX512 decoders. Choose a driver and decoder with at least 1 kHz PWM (16 kHz for camera-facing work) to keep the run flicker-free on video.

Question 11

Can I order a custom RGB LED strip?

Accepted Answer

Yes — LED count, pitch, PCB width from 5 mm, copper weight, cut unit, IP class and connector type are all configurable, including RGB+CCT (five-channel) and mixed RGB/white layouts. DENO is a manufacturer, so a non-standard colour build is tooled from an existing FPCB stack-up rather than quoted as a new product line.

Question 12

What is a multi colour COB LED strip?

Accepted Answer

A multi colour COB LED strip puts two or more channels under the same continuous phosphor line, so the colour changes but the dots never appear. DENO builds CCT (dual white), RGB, RGBW and SPI addressable versions from 360 to 840 LEDs/m at 24V, all cut-to-length and all dot-free at 180°.

Question 13

Should I choose CCT, RGB or RGBW COB LED strip?

Accepted Answer

Choose CCT when the space only needs white light that shifts from 2700K to 6500K, RGB when colour is decorative, and RGBW when one line must do both — saturated colour for events and a proper white for everyday use. RGBW costs more per metre but removes the second strip most projects otherwise install.

Question 14

Can colour changing COB tape dim smoothly without flicker?

Accepted Answer

Yes, with a PWM driver above 3 kHz or a flicker-free constant-voltage supply. Because the phosphor line is continuous there is no stroboscopic dot pattern for a camera to catch, so DENO multi-colour COB tape is a common choice for studios and retail spaces filmed on phones.
