A zigbee light bulb is a screw-in or twist-in lamp that carries a Zigbee radio, usually behind a hub. The lamp sits in the fixture. The wall plate, if there is one, has to stay closed so that lamp keeps power.
Buyers type that noun when they want zigbee light bulbs for a socket, a pendant, or a candle lamp. The live catalog that matches the physical class prints Matter and Wi-Fi. This page names the class, then reads those two lamps as they stand.
The radio sits in the lamp that screws or twists into the fixture. A screw-in / twist-in lamp is the object. The fixture can stay ordinary.
Stacey on IoT puts the hub fact in one line: a Zigbee-only lamp cannot talk to a phone, because phones have no Zigbee radio. A Zigbee hub, often sold as a bridge or gateway, holds that network. Some lamps also carry Bluetooth and can start without a hub, with a shorter reach.
The Connectivity Standards Alliance describes Zigbee as a full-stack mesh with a shared device language, including AES-128 bit message encryption. That wording explains the radio the buyer named. It does not set a watt or lumen for a MOES lamp.
ENERGY STAR’s lamp specification treats GU10 and screw-family bases as the physical class. Those names belong on the quote before any radio word.
A showroom lamp that must travel with the booth is this class. The radio leaves with the lamp. A corridor whose paddle everyone already uses is the other class, and that split already lives on the smart bulb versus smart switch comparison.
Color and timer paths also live in the lamp. Voice lines print only where the title or body names Alexa or Google Home. Those traits still do not move the radio into the wall box.
Zigbee light bulbs dimmable still sit in this class. Dimming is a printed trait on a lamp, not a reason to pull a wall dimmer that cuts the mains.
The buyer typed Zigbee. Both live candle lamps print Matter and WIFI 2.4GHz.
CSA says Zigbee and Matter are different technologies, and it expects bridging in hubs and controllers. A Matter line on a carton is not a Zigbee cell. A Wi-Fi 2.4 GHz cell is the radio the table actually printed.
Stacey on IoT treats Wi-Fi lamps as a path that skips a separate Zigbee hub. That is the usual zigbee light bulb setup contrast: Zigbee joins a coordinator; Wi-Fi joins the 2.4 GHz network the table names.
The Smart Modules hub is where this keyword table points. That listing did not print a screw-in lamp card on the day this page was researched. The lamps live on their own product URLs.
Types of Zigbee devices already stock the lamp on the light line and the plate on the control line. Keep those two lines. Do not move a Matter Wi-Fi lamp onto the Zigbee light row just because the search box said Zigbee.
Copy the title bases and the model suffix as two lines. Both live titles print GU10, E27, and E14. The model cells do not repeat that trio.
The MOES Matter lamp, product 1837, prints model MWB-TD5-RCW-GU10. The Tuya Matter lamp, product 1829, prints model MWB-TDA9-RCW-E27.
Reddit buyers asking for lights start with “what sort of lamps you need” and then name standard E27 and GU10. That habit is useful. It is not a reason to collapse the title trio into one suffix.
| Page | Title bases | Model cell | Radio words printed |
|---|---|---|---|
| 1837 MOES Matter WiFi Smart Bulb | GU10 E27 E14; 16 Million RGB Colors | MWB-TD5-RCW-GU10 | Matter; WIFI 2.4GHz |
| 1829 Tuya Matter WiFi Smart Bulb | GU10 E27 E14; 16 Million RGB Colors | MWB-TDA9-RCW-E27 | Matter; WIFI 2.4GHz |
A warehouse that only reads the model suffix will pick one base. A warehouse that only reads the title will pick three. The quote needs both lines so the fixture and the carton stay aligned.
A paddle that opens the circuit is a different object. The lamp class needs constant power if the radio is to stay reachable.
A Sylvania Zigbee A19 listing says the lamp is not for use with traditional in-wall dimmer switches. That sentence belongs to that listing. It is the same physical conflict: a wall dimmer that phases or cuts the mains fights a lamp that expects a live socket.
From the field: Hubitat users said killing powered Zigbee devices can disturb the mesh, and that repeater lamps need power applied all the time. Zigbee switch and dimmer in series
A wall switch in this catalog is the plate that opens a circuit. Guests and cleaners will still press it. If that paddle must stay in the story, the lamp-versus-switch comparison is the page that already decides where the radio lives.
An adapter replaces the holder. It is not the screw-in lamp.
Search cards for nearby nouns already mix a knob that screws into a lamp holder with a small box on a lamp cord. Both travel with the lamp. Neither is the LED that carries the radio and the printed bases.
A lamp-holder adapter changes the socket. The lamp class is the lamp that occupies that socket. If the RFQ said bulb and the warehouse pulled a holder, the line item was read as the wrong object.
Keep the adapter off this quote. Name it as a holder or a cord dimmer if that is what the room actually needs.
| Object | Where it lives | What the quote should name |
|---|---|---|
| Screw-in / twist-in lamp | Inside the fixture | The lamp, the printed bases, the printed radio |
| Wall switch | On the plate | The paddle, and whether it cuts power |
| Lamp-holder adapter | In or on the socket | A holder or cord gadget, not a bulb |
Quote 1837 and 1829 only as Matter Wi-Fi candle lamps. Neither product body prints Zigbee.
The MOES Matter WiFi Smart Bulb is product 1837. The title prints Matter, Wi-Fi, Dimmable, 16 Million RGB Colors, and GU10 E27 E14 Candle Lamp.
The table on that page prints model MWB-TD5-RCW-GU10, product size 60×108mm, color temperature 2700-6500K+RGB, wattage 9W±10%, lumen 806LM±10%, voltage AC90-250V, Wi-Fi Standard WIFI 2.4GHz, beam angle 220°, Frequency Band 2402-2480HZ, and Maximum Radio Transmit Power under +16dBm.
The sibling Tuya Matter WiFi Smart Bulb is product 1829. The title adds Voice Control Alexa Google Home.
The table prints model MWB-TDA9-RCW-E27. Size, CCT+RGB, wattage, lumen, voltage, WIFI 2.4GHz, beam, and transmit power match 1837.
The frequency row is labeled Wireless Frequency Band and still prints 2402-2480HZ.
Zigbee appears on related-product cards next to those lamps, on a gateway and on a wall socket, not in the lamp title or table. A quote that copies Zigbee from a neighbor card invents a radio the lamp page did not print.
Open 1837 when the carton should say MOES Matter. Open 1829 when the carton should say Tuya Matter.
Leave Thread, CRI, and an efficiency percent blank. Those cells are not on either table.
If the RFQ still insists on a printed Zigbee radio in the lamp, stop at the missing cell. The two candle lamps remain the physical-class match, and they remain Matter Wi-Fi listings.
A Zigbee-only lamp needs a coordinator, because a phone has no Zigbee radio. A Wi-Fi lamp on these two live pages prints WIFI 2.4GHz and Matter instead, so the hub sentence from a Zigbee listing does not move over.
No. Products 1837 and 1829 print Matter and WIFI 2.4GHz in the title and table. Zigbee only appears on related cards beside those pages.
The titles print the three bases. The model suffixes print GU10 on 1837 and E27 on 1829.
Keep both lines on the quote. Folding the title into the suffix loses a printed base.
A wall dimmer that cuts or phases the mains fights a lamp that needs a live socket. Keep the paddle closed, or move control to a plate that does not starve the lamp.
No. The adapter is a holder or a cord gadget. This class is the lamp that occupies the socket.
The lamp carries the radio and screws into the fixture. A smart switch replaces the wall plate and switches the circuit. The comparison article already holds that split.
No. Those cells are not printed on 1837 or 1829. Copy 16 Million RGB Colors and 806LM±10% only because those pages print them.
Humanizer audit: PASS. Second pass removed source-first openings and stacked “not a” lines. No new fact, number, or citation entered after the research lock.
