It was rebranded as the Simplex 35 in the 1960s, and the last model for general cinema use following the traditional single lens design was the Simplex PR-1014. The X-L also served as the basis for a number of other models, including those with lens turrets, studio models capable of reverse operation, and a dual-format 35/70 projector. | It was rebranded as the Simplex 35 in the 1960s, and the last model for general cinema use following the traditional single lens design was the Simplex PR-1014.

The Simplex X-L replaced the [[Simplex E-7]] and other earlier models. Some of the main improvements in the X-L include a conical shutter for improved light output, an enclosed oil bath to maintain constant lubrication of the drive system, and the option of a water-cooled gate. It was also the first Simplex to offer the option of a curved gate to improve focus stability. | The Simplex X-L replaced the [[Simplex E-7]] and other earlier models.

The X-L was | The X-L was compatible with the existing [[Simplex SH-1000]] soundhead (also called the 4 Star soundhead) and new units branded as X-L soundheads were also released. The primary distinction between X-L soundheads and the SH-1000 was an additional compartment below the exciter lamp to house a preamp. In the 1960s the X-L models were replaced by the [[Simplex 5 Star]] soundhead, which replaced the gearbox of the earlier models with a belt drive. The X-L was also designed to be compatible with soundheads manufactured by RCA and others. | ||
The design of the X-L remained largely unchanged for decades, with few differences that would impact daily use. One notable exception is the oil gauge and filler, which was originally located on the front of the mechanism. The gauge was replaced with a sight glass inside the film compartment, and the oil filler was moved to the top of the mechanism. | The design of the X-L remained largely unchanged for decades, with few differences that would impact daily use.
