Ampoule LED MR16 12 V à intensité variable, 5 W ou 7 W

The MRSP-A001 is the MR16 bulb for the fittings that run on a low-voltage transformer: the landscape spots, the display cabinets, the kitchen under-cabinet strips and the older track heads wired for 12V. It is a dimmable COB replacement in the MR16 format — 50mm across, 50mm tall — and it drops into the socket the halogen MR16s were running.

The COB source

The light source is a single COB chip, which is what gives the bulb its even 115° beam: one light surface rather than a ring of SMD points, so the pool of light on the floor or the shelf reads smooth from edge to edge. Output is 450 lumens from 5 to 7 watts, roughly the halogen MR16 50W replacement class, and CRI is above 80 — the level that keeps the displays and the kitchen work surfaces reading true under it.

The 12V supply

The bulb runs on AC12V, which means it sits on the low-voltage side of a transformer — the electronic or magnetic type the 12V halogen fittings already carry. That is the one thing to check before ordering: the transformer must be LED-compatible, because the old halogen transformers were sized for 50W loads and some electronic types will not run a 7W LED cleanly. Match the transformer to the bulb, or replace it with an LED driver, and the rest of the swap is the socket.

Colour temperatures

Five colour options cover the practical range: 2700K, 3000K, 4000K, 5000K and 6000K. The 2700K and 3000K bins are the residential and hospitality warm whites; the 4000K is the neutral working light; the 5000K and 6000K bins suit the display and retail positions that run cool. The CCT is fixed per bulb and chosen at order time, so the fittings in one room should order the same bin.

Dimming

The bulb dims on a Triac dimmer, the leading-edge or trailing-edge type on the 12V side. Match the dimmer to the bulb the way any low-voltage dimming circuit expects — the dimmer, the transformer and the bulb as one chain — and the fade runs cleanly. On the fittings without a dimmer, the bulb switches on and off from the circuit like the halogen it replaces.

Body and build

The body is PC in white, 50×50mm, IP42 rated for the dry indoor fittings — the cabinets, the under-cabinet strips, the interior track heads. It is not a wet-position bulb, so the outdoor landscape spots need a rated fixture around it or a sealed fitting. The bulb carries SAA, CE and RoHS certification with a two-year warranty.

Où est-il utilisé ?

Kitchen under-cabinet strips on a 12V transformer, where the 115° beam covers the work surface. Display cabinets and retail shelves, where the COB’s even field lights the merchandise. Landscape and garden fittings in sealed housings, running on the low-voltage supply. And the older MR16 track and recessed heads, where the halogen capsules are being swapped out one by one for the LED replacements. In each of these the swap is socket-for-socket: the MR16 pins push into the same holder, the transformer stays or is upgraded to an LED driver, and the fitting keeps its beam angle and its light level.

Choosing between the range

The decorative bulb range splits by socket and supply: the MRSP-A001 is the MR16 on AC12V for the low-voltage fittings; the GUSP-A001 is the GU10 on the mains, for the fittings that run the bulb directly from the wall supply. The choice is made by the fitting, not by preference — an MR16 socket takes the 12V bulb and a GU10 socket takes the mains one, and the two are not interchangeable. If the fittings are being replaced anyway and the wiring is being simplified, moving to GU10 mains fittings removes the transformers entirely; if the 12V infrastructure stays, this bulb is the drop-in.

Why do buyers pick the MRSP-A001 over the alternatives? Here is what we hear from customers:

One COB, one even beam. The cheaper MR16 LEDs run a ring of SMD points and the beam shows them; the COB here gives a single smooth 115° field, which is what the display cabinets and the work surfaces need.

The halogen replacement class. 450 lumens from 5 to 7 watts covers the 50W halogen MR16 output, so the fitting keeps its light level and drops the draw to a fraction.

Five colour bins. 2700K through 6000K covers the warm residential look to the cool retail display, ordered per fitting so the room runs one bin.

Triac dimmable. The bulb fades on the standard Triac dimmers the low-voltage circuits already carry — matched to the transformer, the dimming is clean.

Certified and warranted. SAA, CE and RoHS, with a two-year warranty on the bulb.

The MRSP-A001 drops into the 12V fittings that were built for halogen MR16s: the under-cabinet strips, the display cabinets, the landscape spots and the older track heads.

Kitchen under-cabinet strips. The 115° beam covers the work surface evenly from the strip under the cabinets, and the 4000K bin is the usual choice for the working light.

Display cabinets and retail shelves. The COB’s even field lights the merchandise without the dotting an SMD bulb shows, and the 3000K bin keeps the displays warm.

Landscape and garden fittings. The sealed outdoor housings on the 12V supply take the bulb, with the transformer indoors or in the weatherproof box and the IP42 bulb sitting inside the rated fixture.

Older MR16 track and recessed heads. The halogen-to-LED swap, socket for socket: pull the halogen, push the MRSP-A001 in, confirm the transformer and the fitting keeps its light level.

Hotel and hospitality fittings. The 2700K and 3000K bins over the guest areas, dimmed on the Triac circuit for the evening, with the two-year warranty covering the maintenance cycle.
