Red, Green and Blue LEDs, Strips and Indicators

Red, green and blue LEDs: color choices versus true RGB

This collection brings together discrete red, green and blue light-emitting diodes, LED chips and filaments, flexible COB and SMD tape, pilot indicators and finished colored lamps. The phrase “red green blue” often lists alternative single-color variants: a chosen red strip emits red, a chosen green strip emits green and a chosen blue strip emits blue. It does not mean the same unit blends all three colors. Only an explicitly selected RGB or other multichannel variant supports color mixing, and even then controller, channel wiring, supply and package contents must be checked. The assortment also includes warm/cool white, yellow, pink, UV and IR options as well as a laser module, so determine the actual output and safety class of the selected product before purchase.

Shop by component and assembly level

• Bare through-hole LEDs: 3, 5, 8 and 10 mm round, flat-top, straw-hat, oval and rectangular parts, with clear or diffused lenses and assorted single-color or blinking variants. Choose body geometry, lead orientation, color, quantity and current rating.
• High-power and SMD emitters: 2835, 5050, 3535 and 5730 chips, COB integrated light sources, and some LEDs pre-mounted on 16/20 mm star PCBs. These are components requiring appropriate drive and heat management, not mains-ready lamps.
• Flexible light sources: 3/5/8/10 mm COB tape, 2835/5050 strips, diffused neon-style strips and flexible COB filaments offered with separate 3/5/12/24 V and plug-powered configurations.
• Finished lights: E10/E12/E14/E27/G9/GU10/GU5.3 lamps, panel pilot lights, display modules, warning lights, floodlights, keychain torches and stage fixtures use their own sockets and electrical ratings.

Do not apply one item's wavelength, IP rating, power, current, color rendering, brightness or safety statement to the whole collection. A 3 V filament, 5 V USB tape, 24 V strip, 220 V lamp and 22 mm mains-rated pilot light serve entirely different electrical designs.

Discrete LED packages: geometry, color and drive

Bulk LED families in this series include 3 and 5 mm flat-top and round parts, wide-angle straw-hat lenses, 504-style oval indicators and 2 × 5 × 7 mm or 2 × 3 × 4 mm rectangular LEDs. Lens shape controls how light is distributed; “ultra bright” in a seller title cannot establish the same luminous intensity or viewing angle for every package. Clear-lens LEDs may appear nearly colorless until powered, while a colored diffused lens can visibly indicate the nominal color when off. Check cathode marking and lead length in the specific datasheet rather than assuming a generic long-lead rule on pre-cut bulk lots. Assortment kits and 50-, 100-, 500- or 1,000-piece lots differ; a selected Red option in a 1,000-piece listing is not necessarily an assorted-color box.

Some 5 mm two-color devices have a common-anode or common-cathode arrangement and can produce two selectable colors, whereas a single-color red, green or blue two-lead diode has one junction. “RGB Fast” and “RGB Slow” flashing selections can contain internal oscillation electronics, unlike plain externally controlled RGB LEDs. Flashing red/green/blue or cycling RGB prewired LEDs should not be sold as individually programmable pixels. Typical color and forward-voltage claims in seller titles, such as red around 2 V and blue/white near 3 V, are not universal operating supplies; match the selected part's forward-current and voltage limits, use current limiting and confirm the chosen pinout. An integrated resistor in a 12 V prewired diode is not present in an unmodified 3 V bare LED.

SMD and high-power emitters are not finished bulbs

2835 and 5050 surface-mount parts, 3535 ceramic emitters, 5730-on-board assemblies and 1/3/5 W-class LED packages offer red, green, blue, white and sometimes UV/IR wavelength selections. The color choice can change forward voltage, power handling and optical output; a “0.1 W red” 5050 variant and a “0.2 W green” selection are not the same electrical device. A 5050 RGB package has multiple internal color junctions, unlike a fixed-color 5050 SMD LED. Match footprint, pad polarity, thermal layout and the exact selected specification. Do not attach a nominal 3–3.6 V claim from a royal-blue option to a red junction that the same listing describes with a lower voltage.

High-power LEDs on 16 or 20 mm star PCBs are easier to mount than an unsoldered bare chip, but the star board is a carrier and heat spreader, not automatically a regulated driver, heatsink or waterproof fixture. A 1 W or 3 W marketing class does not prove the exact forward current or allowable junction temperature. Larger 10/20/30/50/100 W integrated COB products have particularly important current, voltage, thermal and optical distinctions by variant. “Driverless” or “smart IC” on a particular seller's listing must be checked against the actual module design and supply rating; it does not make every COB safe for direct connection to mains. For UV, near-UV, infrared and grow-light wavelength choices, use product-specific optical and safety data; neither horticultural effectiveness nor eye safety follows from a general “full spectrum” title.

COB and SMD strips: match supply, width and length

USB 5 V COB selections include nominal 320 LEDs/m at roughly 8 mm width and ultra-slim 2.7, 3 and 5 mm PCB options in separate listings. Fixed colors include red, green, blue, ice blue, yellow, pink and several whites. Select the actual emission and length, from short 0.5 m samples to some 5 m USB selections. A USB connector does not imply that a TV or laptop port can power every length; use the selected product's watts per metre and the available source current. Some 5 V tape ships with a 3AA battery box, while another 3AA option is a separately packaged strip kit. Check whether cells are included and estimate runtime from the actual load and battery chemistry. A 3AA box, 5 V USB port and 12 V adapter are not interchangeable even if all three variants use COB LEDs.

Higher-density 480/528 LEDs/m COB families offer separate 12 and 24 V DC variants, 8 or 10 mm PCB choices, fixed red/green/blue or warm/natural/cool white, and lengths typically 0.5–5 m. One option encodes “12V 528Leds-10mm PCB” while another encodes “24V 480Leds-8mm PCB”; read the complete selection before choosing a channel, diffuser and supply. Nominal LED count per metre indicates layout density, not equal watts, cut pitch or brightness. Other 320 LEDs/m 12/24 V tape and 120 LEDs/m 2835 tape use different power demands and visible dot spacing. Long narrow runs can experience voltage drop, and power distribution should follow the selected strip's specification. Fixed single-color two-wire tape cannot generate a full RGB palette without separate red, green and blue channels built into the tape.

Where a 12 V 2835/5050 strip offers “RGB,” “RGBW” or “RGBWW” alongside red, green, blue and white, those are different circuit configurations and require the matching channel controller. A 24 V product with separate IP68-marketed construction differs from a plain IP20 uncoated strip, but IP language for a product does not establish protection of field-cut ends, joints, control boxes or power supplies. Neon-style diffused rope also has physical size and bend limits that differ from bare adhesive PCB tape. “Waterproof,” “for pool” or “underwater decor” is not permission to submerge an assembled circuit unless the exact selected system, including terminations and supply isolation, is rated and installed for that environment.

High-voltage flexible lights and plug kits

Some 2835 and COB listings advertise 220 V mains-powered strips from approximately 0.5 m to tens of metres, sometimes with EU plug, inline dimmer or timer choices. They are different from low-voltage DC tape even when emitting-color options overlap. Select plug, rated regional supply, length, control assembly and cut/end-seal instructions for the exact kit. Do not connect a 5/12/24 V strip to a mains strip's plug or treat a dimmer as universally compatible. An advertised waterproof coating or IP rating on a bare length does not certify the installation after trimming and reconnection. Mains lighting should be installed to its actual instructions and local electrical requirements; this collection page is not an electrical connection diagram.

Flexible filaments and lamp bases

COB “Edison” flexible filaments appear in short lengths around 25–450 mm and some longer choices, with red, green, blue, warm/cool white, pink or purple options and separate nominal 3, 9, 12 or 24 V marketing labels across different product families. They are light-source components for a designed lamp, not completed E27 bulbs. Check the actual filament's operating current, required driver, bend radius, thermal conditions and polarity. A five-piece 12 V 120 mm COB bar or single 200 mm 12 V light source is a different mechanical assembly. The individual filament's stated “3 V” cannot be transferred to a mains-rated E27 decorative bulb merely because both may be used in a lamp.

Finished screw and pin-base lamps include E10 instrument bulbs with separate 3, 3.8, 4.5, 6, 8, 12, 18 or 24 V listings, E12/E14 miniature bulbs, E27 110/220 V decorative lamps, G9 220 V colored lamps, and GU10 versus GU5.3 spotlights. Check base and selected supply together: GU10 and GU5.3 are not plug-compatible, and an E27 12/24/36 V low-voltage bulb must not be assumed safe on an E27 mains socket just because the screw threads match. A 2-piece G45 E27 holiday bulb listing is a pack of selected colored bulbs, not a single color-changing RGB bulb. Some product headlines mix 110 V, 220 V and MR16/GU10 marketing terms; use the actual variant's specific electrical and base information rather than a title's combined list.

Panel indicators and signage

6 mm wired metal indicator lights, 12 mm IP67-marketed pilots, and 22 mm AD16-22DS or square-head AD16-22F panel indicators have distinct hole diameters, bezel shapes, lead/terminal arrangements and voltage options. Selected red, yellow, green, blue or white indicators can be paired with 3/5/6/9/12/24 V DC or particular 110/220/380 V-marketed versions. A 12 V red pilot is not universally voltage-tolerant merely because a sibling variant says 220 V. Verify AC versus DC where relevant, polarity, terminal protection and enclosure sealing. For high-voltage panels, use the selected rating and qualified installation, not an assumed low-voltage LED wiring method. Neon 4 × 10 mm or 5 × 13 mm mains indicator lamps with resistors are not the same technology as a two-pin LED bead.

P10 single-color LED display modules, a ten-segment bargraph board and a TM1637 four-digit module offer different ways to show colored information. P10 is a sign/display panel, a TM1637 is a numeric display, and the bargraph expresses a level: none is an RGB pixel array simply because red, green and blue colors appear as choices. Check interface, scan driver, panel dimensions, pinout and included controller for the chosen module. A 26 mm signal-light pixel cluster for traffic equipment requires its own mounting and electrical specification; its color options alone do not establish traffic-control certification.

Finished warning, stage and portable lights

A 96-LED windshield strobe offers fixed white, red, blue, green, yellow and paired-color selections such as Red Blue or Green White. A paired-color warning product is not necessarily an RGB color-mixing light. Confirm selected color, flash pattern, supply, placement and legal restrictions on warning/emergency colors before use. Shoulder warning lamps and bolt-mounted N-5041 warning products have their own power and steady/flashing choices. A Bluetooth-controlled 5 W stage scanner and a 50 W RGB outdoor floodlight are finished fixtures with controller and mains or DC requirements that differ from loose LEDs. Seller IP66 and “outdoor” statements apply only to the identified fixture and do not cover exposed junctions in an installed system. A four-color white/red/green/blue zoom flashlight and compact keychain torches are portable products whose cell, charger, mode and contents need checking separately.

The catalog also includes a red/blue/green laser-module listing. A laser diode is not a wide-angle LED; its concentrated beam, wavelength, power, driver and eye-hazard classification must be evaluated for that precise selected module. Do not use an LED current estimate, an RGB stage-light controller or a generic decorative-lamp instruction to power a laser. UV and IR emitters similarly require wavelength-specific safety and handling; visible appearance alone is not a reliable sign of exposure.

How to choose confidently

1. Specify function: bare LED, prewired diode, SMD chip, star-PCB emitter, flexible filament, strip, pilot light, display module or complete luminaire.
2. Specify the actual optical selection: fixed red, green or blue, other fixed color/white tone, bi-color, self-flashing RGB or controllable multichannel RGB/RGBW. Do not equate a list of alternatives with multicolor output.
3. Match electrical input: bare junction forward current versus integrated-resistor prewired 5/12/24 V, low-voltage tape, battery assembly or product-specific AC mains fixture.
4. Match geometry: 3/5/8/10 mm lens, SMD footprint, star PCB size, tape width/density/length, filament length, panel cutout, bulb base and pack quantity.
5. Confirm controls and delivered contents: bare strip versus kit, dimmer, remote, battery box, power supply, connectors, driver and whether the color comes from a single LED or multiple channels.
6. Check environment and use restrictions: credible per-product ingress protection including joints, thermal management, laser/UV/IR exposure, and local rules for vehicle or warning lights.

Read the exact chosen variant and its product specification before purchase. Seller claims about certification, wavelength, lumens, waterproofing, lifetime, color rendering or universal compatibility are not collection-wide guarantees.
