Well, if you cannot get drops of better gear with more light, then you are going to have to purchase gear from vendors.
Use your vanguard and crucible marks to buy purple gear and equip it.
If you are having trouble getting shards to level up your purple gear. Do the same, but break down the gear you buy. Do the daily for a chance for 2 shards, on lvl 28. Also, try doing daily public events.
lol.. of course, you need to be a higher level to do 28's lol
Good luck, friend.
