While in orbit, put on your highest ranked gear and then go to a cryptarch to decrypt engrams. Although some gear might appear at the light level you got that engram at, you have a chance to get gear at a light level equal or greater to what your current level is. That's how I got my 295 blues. I then infuse my legendary gear and just repeat. Worked well for me so far. I've gotten a few 300 and 290+ gear.
