Logo: Against a black background, two rainbow light beams shoot into a crystal, triangular panel laying down. Then, a ball containing a "G" covering most of its contents and "LEM" on the top right of the sphere, rises from the glass object. Underneath, "GLEM Productions" flies in and slides from the right respectively.

Logo: Set on a black- gradient background, two, shiny objects fly in: a glass ball and a right triangle with rounded edges. The former rests over the latter shape while two rainbow light beams shoot in from the top left corner of the screen and the center left border of the right triangle, intersecting near the centre of the screen. The former light ray passes through the glass ball, creating an expanding radial rainbow stripe on the top portion of the sphere, stopping before it can make it to the ball's centre. The company name in white and capitalization then fade in on the bottom right.

Variant: An in-credit variant exists. Here, the rainbow beams consist of three colours:, , and. Plus, the text on the sphere, resembling its appearance in the next logo, is visible with the ball in dodger blue and the text in.

Technique: CGI.

Audio: A dramatic and exciting fanfare with build up to an alternate take of the horn stinger from before.

Logo: On a space starfield, the inside of a transparent version of the GLEM logo rotates and zooms out. In the background are three lines circling around the logo coloured in, , and respectively. After the logo zooms out, a spherical version of the logo appears with the same movement as before. Alongside it, the lines fly away from the screen and a long, triangular surface flies in from the bottom. After both the surface and sphere stop moving, two rainbow beams shoot in within similar positions as before.

Technique: CGI.

Audio: An alternate rendition of the previous logo's jingle.

Audio Variants:
 * Sometimes, a rock rendition of the fanfare is heard.
 * Starting in 1998, an alternate rock fanfare with a similar structure as the normal jingle is used.

Availability: Like the previous logos, it appeared on non-scripted programs from the mid to late 1990's, which include the last several episodes of the original run of Sacrée Soirée, Sans aucun doute until 2000, Intervilles until 1999, among a few others.

Logo: It starts off on a black-dark blue gradient background with a thin white outline of a tube button in the center. A female hand presses the button with her pointer, illuminating the company name in a wide, blocky font inside a white tube. The colour of the box shines and becomes while  scan lines of varying thickness scroll vertically in the background. A outline of a top right corner appears near the logo as the box continues to shine, this time illuminating white and  lights.

Technique: A mix of live-action and CGI.

Audio: There is a soothing electronic ambience in the background for the entire logo. A boom followed by electronic buzzing is heard when the finger presses the button.

Availability: It appeared on the TF1 run of L'Île de la tentation and the revival of Sacrée Soirée.
