Optima L-21 double lamp holder for G4 bases
This Optima L-21 holder accepts bulbs with G4, GU4, GX4 and GZ4 bases such as MR11 and two-pin G4 types. It provides two sockets in a single unit for installations that need paired low-voltage lamps. Each socket is rated for a maximum of 100w at 25V.
Dual socket layout simplifies paired bulb wiring
The double design lets you connect two compatible bulbs from one mounting point, reducing the number of separate holders required. This arrangement suits fixtures built for twin MR11 or similar capsules. Buyers needing a single socket or a different base type should choose an alternative holder.

Questions about this item
Will the ceramic sockets or internal wiring need replacement after extended use?
The holder uses standard G4/GU4/GX4/GZ4 sockets rated for 100 W at 25 V each; only the bulbs themselves require periodic replacement.
What thermal or electrical limit is reached first when both sockets run at full load continuously?
Each socket is rated for a maximum of 100 W at 25 V, so the 100 W per socket limit governs sustained operation.
