So it's kind of unclear as to the exact numbers required for each gear levels. I found the answer over at the gamefaqs forums: [url]http://www.gamefaqs.com/boards/704532-destiny/70114282/797003001[/url] If you don't want to click the link then it goes as follows: Level 21 - 20 light Level 22 - 32 light Level 23 - 43 light Level 24 - 54 light Level 25 - 65 light Level 26 - 76 light Level 27 - 87 light Level 28 - 98 light Level 29 - 109 light Level 30 - 120 light
