Added in Afterbirth †

Dim Bulb is a trinket added in The Binding of Isaac: Afterbirth †.

Effects[]

  • Increases all stats while Isaac's active item is completely uncharged:
  • Items that charge automatically will get only a tiny moment of benefit from the Dim Bulb before they gain more charge again.
  • Removed in Repentance If Isaac's active item has no charge bar and can used anytime, like 15►How to Jump How to Jump, Dim Bulb's effects will be permanent.

Notes[]

  • Dim Bulb is more than twice as powerful as Vibrant Bulb Vibrant Bulb; however, its effects are active less frequently.
    • However, 1 room charge items can be used at the start of each room to effectively get the Dim Bulb's effects constantly.
  • Dim Bulb has no effect when no active item is held.
  • If the player has 2 items (via 15►Schoolbag Schoolbag), only 1 of them needs to be empty to receive the benefits.
    • This appears to have been patched out on PC. Removed in Repentance However, if one of your two active items has no charge bar (e.g. 15►Remote Detonator Remote Detonator), you can swap to it after using the charged item to preserve the Bulb's effect.
