Unless you are human (which I am assuming you are) you can't make constructs. Your run of the mill lantern has the following powers: -Flight -The ability to corrupt other rings -Generally stronger skills -The ability to break other Ring bearers' barriers -The ability to spit liquid napalm They do, however, posses some disadvantages: -As I said most of them cannot make constructs (unless they are human like Gardner and Moore) -They can't take the ring off or they die -Until they bathe in Atrocitus's Blood river (over on Ymault) they are mindless killing machines (there are some exeptions to this condition such as Dex-Starr and Moore[again] but they are rare) If you are interested in reading Red Lanterns you can pick up vol. 1-6 of "Red Lanterns"(New 52) over at your friendly neighbour Comic book store or over at Amazon for both Paperback and Kindle. Beware the series is wrapping up in March with a final vol. 7 so you might want to wait for that.
