I've been reading with great interest the various posts here and elsewhere regarding low voltage lights, and how they are not allowed to be closer than 10ft. from the water's edge. Some people say that it's dangerous, others say that with a pool-specific transformer it's perfectly safe (though still a code violation).
Regardless, I came across this recent article that seems to indicate a change in the code is in the works.

In the 2011 and previous editions of the National Electrical Code (NEC), installing low-voltage lighting in close proximity to the edge of a swimming pool was a Code violation, yet almost every backyard swimming pool with a landscaped yard has low-voltage lighting too close to the pool’s edge. Low-voltage lighting systems are not permitted to be installed within 10 feet of the nearest edge of the water for a pool, spa or fountain, unless otherwise permitted by Article 680. With the acceptance of new text in 680.22(B)(6) of the 2014 NEC, many of these installations will now be compliant.

The proposed new 680.22(B)(6) states: “Low-Voltage Luminaires. Listed low-voltage luminaires not requiring grounding, not exceeding the low-voltage contact limit, and supplied by listed transformers or power supplies that comply with 680.23(A)(2) are permitted to be located less than 1.5 m (5 ft) from the inside walls of the pool.” Section 680.23(A)(2) states that transformers used for low-voltage lighting around pools shall incorporate isolated windings with an ungrounded secondary and a grounded metal barrier between the primary or secondary or double insulation between the primary and secondary windings. This change should provide safety for low-voltage lighting systems close to pool or spa edges.
