This was a segment on the "Superman-Aquaman Hour of Adventure". Hal Jordan, other wise known as Green Lantern, protects the Earth from evil villains and aliens who try to take it over or destroy it. His power ring can emit a holographic image of anything he wants it to which might help him out in his situation. Every 24 hours he has to recharge his ring with his lantern which he keeps hidden back at his home. He was given his powers by the protectors of the galaxy, a council of big-headed blue guys who notify him when there is serious trouble afoot. He is also helped by his sidekick, Kiro, a blue vulcan-looking being. Most of the time the Green Lantern has to save Kiro from the evil beings.
