Satco 9551 MR11 LED Flood Bulb

The Satco 9551 is a 1.6-watt MR11 LED flood bulb operating on 12 volts. It produces a 5000K colour temperature with a 40-degree beam angle for focused illumination. This standard bulb suits landscape, accent or display lighting where a compact flood source is required. It replaces a 3800-watt halogen equivalent while drawing minimal power.

Thermals Noise and Power Draw

The LED design runs cooler than the halogen it replaces, reducing heat build-up in enclosed fixtures. With only 1.6 watts consumed, the load on a 12-volt transformer is very light. Silent solid-state operation adds no audible noise to the installation. The transparent envelope allows full light output without diffusion loss.

40-Degree Beam Angle Constraint

The fixed 40-degree spread determines where this bulb works best; wider wash or narrow spot needs cannot be met. Buyers who require a different beam angle must select another model. The 5000K colour temperature is also fixed, so warmer or cooler white preferences are not supported. Transparent finish suits open fixtures but may show the LED array directly.

Questions about this item

How do I install the MR11 12 V bulb without damaging the pins?

Align the two bi-pin contacts with the GU4 socket and press straight in; forcing at an angle bends the pins and breaks the ceramic base.

What part will need replacement first on this 1.6 W LED?

The internal driver electrolytic capacitor ages fastest; once it dries out the lamp flickers or fails to start.

What limit appears first during continuous operation of this 5000 K flood?

Junction temperature reaches its maximum after roughly 3800 hours, causing output to drop below useful task levels.
