Sarah is an attractive woman, with a heart-shaped face, full lips, and straight blonde hair.
As Lady Photon/Photon Mom, Sarah wears a white bodysuit without a mask. The bodysuit features a starburst on the chest with lines from the star's edges extending around her body, changing color from indigo to purple as they get further from the center. She also wears a tiara to keep her hair out of her face, in the same general style as the starburst image.
After the resurrection her facial features are still recognizable, albeit she looks younger and her eyes had their colors changed, with black scleras, bright purple irises and white pupils. She wears purple and black. Her emblem has Valkyrie's wings added to it.
Sarah has the ability to fly, create energy blasts from her hands, and create forcefields.
She could gather energy in her hands, which she "spent" to shoot sprays of laser blasts. She was strong enough to blast through Marquis' bone plates in one shot, and had to hold back to avoid firing through them and accidentally harming a teammate. People reacted as if they were punched when hit. Even fired individually, several successive blasts were enough to beat a person to a pulp.
Her shields were broad enough to protect other people, described as a "wall of light", transparent.
She has demonstrated an ability to use her forcefields as a first aid measure - shaping them to cover a wound - though they are rooted in place unless she makes them a bubble around herself.. She could create a small forcefield to help her lift someone.
Her powers are more rounded-up compared to powers of her kids, who are more specialized.
She is resistant to blinding lights in the same way as her sister, and additionally can see in the dark.
She was responsible for honing out fliers formations, which later will be incorporated by PRTCJ via her daughter. Sarah and her kids also used their forcefields as a form of coded communication.
↑ 2.02.1Lady Photon – Head of New Wave, flies, can create lasers and generate forcefields, known to some as Photon Mom. Wears a white bodysuit with a purple/indigo starburst featured as an emblem. - Cast (spoiler free)
↑The leader of New Wave had named herself Lady Photon, but in the wake of New Wave’s founding, and the revealing of their secret identities, the media had latched on to the idea of a superheroine mom and dubbed her Photon Mom. It was apparent to anyone who followed cape news that the name really bugged her.
Lady Photon’s daughter and niece were in the air with her. Laserdream and Glory Girl. Mother and daughter shared the same general powers; flight, the ability to raise forcefield bubbles around themselves, and the ability to project lasers from their hands. As a consequence, their fight with Purity was something of a light show. - Excerpt from Buzz 7.9
↑ 5.05.1Lady Photon, Sarah Pelham – Arguably leader of New Wave, wife of Manpower, mother to Laserdream and Shielder, sister of Brandish. Known to most as ‘Photon Mom’, to her annoyance. Has the powers of flight, the ability to create a personal forcefield bubble, with various lesser applications, and ‘hard light’ blasts from her hands. Wore a white bodysuit with a starburst motif in an indigo-purple gradient, complete with a tiara. - Cast Page (In-Depth)
↑“Right now she’s the battlefield commander. The mom who was out for two hours every night, minimum, right after dinner or my bedtime, depending on if Eric or me needed help with homework. Sometimes all nighters, napping, then waking up to see us off to school before sleeping again.”
↑ 8.08.18.2Lady Photon and the eighteen year old Laserdream landed beside Armsmaster, making a small splash as they touched down.
You could see the family resemblance. They weren’t supermodel good looking, but they were attractive people, even with their hair wet and plastered to their heads and shoulders by the rain. Both wore costumes with a white base color, had heart shaped faces, full lips and blonde hair. Lady Photon’s costume sported a starburst on her chest, with several of the lines extending around her body, or down her legs, going from indigo to purple as it got further from the center. Her hair was straight, shoulder length, held away from her face by a tiara shaped much like the same starburst image on her chest. [...] More than anything else, though, the two of them had the look of people who had seen half their immediate family brutally and senselessly torn apart over the course of one terrible hour. As though they’d had their hearts torn out of their chests and were somehow still standing. It wasn’t that I had seen anyone in those circumstances before, but that look existed, and they had it. - Excerpt from Extermination 8.5
↑She was a woman with a purple and black costume, her eyes altered so the whites were black and the irises and pupils bright purple and white respectively. - Excerpt from Dying 15.2
↑Deep purple eyes, younger, wearing a costume that was darker than her old New Wave one, but it was clearly inspired by it. The starburst icon at her chest had lines that extended out from the icon and around her body, but the lines had more flair to them, and the starburst icon was framed by two faint wings.- Excerpt from Sundown 17.2
↑My cousin Eric had had the range but his beams were weak. My Aunt Sarah had been middle of the road. Crystal had the strongest beams of the three, the strongest top speed and carrying ability to her flight. - Excerpt from Infrared 19.1
↑She could see in the dark, as a part of her power. Just like bright lights didn’t disorient her. - Excerpt from Infrared 19.1
↑A purple forcefield appeared. The square, which disappeared, then a smaller square below it.
