Beacon of Light is a Holypaladin ability, designed to aid paladins in healing groups of players.
Tips and tactics[]
By far, the most common target of this spell is the tank, since they will be taking the most damage, and therefore will always benefit from it. The paladin then casts heals on the other party members taking damage, which also heals the tank.
The heal on the Beaconed target is delayed by about half a second, which can be dangerous in very healing-intensive situations.
Both the casting range and the effect range of Beacon of Light are 60 yards, significantly larger than the normal 40 yards of most healing spells. This gives the Beacon several extra uses.
Note that you must be within 60 yards of the target with Beacon of Light if you want them to receive your heals. If you are farther than 60 yards, you cannot heal the target with beacon, even if the player with the beacon is within 60 yards of someone you are healing.
The effect of Beacon of Light DOES require that you have line of sight for BOTH the beacon AND your target. This can be a significant concern in certain fights.

Hotfix (2011-02-14):The hotfix to Beacon of Light and [Light of Dawn] on February 11 did not produce the intended results and has been reverted. Light of Dawn should still trigger Beacon of Light.
Hotfix (2010-12-14):Healing done by Beacon of Light is now properly affected by healing modifiers on targets which reduce healing done (i.e. [Mortal Strike]).
Patch 4.0.3a (2010-11-23): Now lasts 5 minutes, up from 60 seconds.
Patch 4.0.1 (2010-10-12): Beacon of Light only transfers 50% of healing (was 100%). Moved to tier 4 (was tier 11).
Patch 3.3.0 (2009-12-08): The effect of this ability will no longer sometimes continue past the duration of its buff. In addition, the duration when used with the [Glyph of Beacon of Light] will now correctly be 1.5 minutes. Finally, the tooltip was corrected to indicate benefitting targets must be in the paladin's party or raid.
Patch 3.2.0 (2009-08-04): The healing amount on the Beacon of Light target is now based on the total healing done (including over-healing) instead of the effective healing done. Radius increased to 60 yards. Multiple Paladins can now have this active on the same target. Buff indicating a player is within range of the Beacon target is no longer displayed.
Patch 3.1.0 (2009-04-14): This spell no longer duplicates the heal on yourself if your target is currently immune to being healed due to being on a vehicle. It will simply not duplicate the heal.
