"greater brightness" is a grammatically correct phrase and can be used in written English.
It is typically used to describe a level or degree of brightness that is higher or stronger than another. For example: - "The new light bulbs emit greater brightness than the old ones." - "The photographer adjusted the camera settings to capture even greater brightness in the photo." - "The sun's rays grew in intensity, creating a greater brightness in the room."

A telescope stationed in outer space is entirely above the atmosphere, however, and receives images of much greater brightness, clarity, and detail than do ground-based telescopes with comparable optics.
In all instances, a greater brightness gain was induced with the in situ solid-state enzymes (0.9 3.0 points brightness increase) than a commercial enzyme control (0.8 2.5 points).
Continuously improving diode stacking, and consequently greater brightness, allow the requirements for laser cutting to be met without the use of further brightness converters (diode-pumped solid state lasers).
She knew the priorities, what was right and wrong, knew what would last and was on the brink of even greater brightness.
Lasers are employed because laser light can be focused into an extremely tiny spot of great brightness.

And for those with poor eyesight, a miniature, MEMS-based VRD would have the advantage that the narrow beam of light shining into the eye would have great brightness and depth of focus making it clear and sharp, regardless of the shape or optical properties of the viewer's eyeball.
