I definitely agree that patience is the best way to increase light level. As many know, drops are completely random and those may take time to materialize. Waiting for higher level drops may get tiring after a while, but I assure you that you'll eventually find something at a higher light level than any part of your gear, so you can infuse it or just change it altogether to raise said light level (If you're not sure how certain pieces of equipment will change your light level, use an online light level calculator to check what the changes may entail. Personally, I use this website: http://jpwilsondesigns.com/destiny/lightcalculator.html as it is very useful and very easy to use.) Usually if I find an item that is a higher light level than my currently equipped gear, I only infuse it if it's a little bit higher than the original, because light levels will vary depending on if it's a lot higher or closer to the base level. THIS is where the light level calculator (listed above) comes in handy. Court of Oryx nearly always has pretty high light level gear to obtain by doing runes (You're almost always guaranteed one or two engrams to drop after a rune is completed and is placed by you. There's also a chance at just getting already decrypted guns and armor.
