Cable track lighting systems are elegant, only good for 300 Watts
12V LED lamps save an overloaded track lighting system
I recently encountered a fine mechanical installation of a cable track low voltage lighting system that was electrically overloaded. The cable track cable is good for 300W. That’s six (6) 50W lamps. Many installations will benefit from new high-efficiency LED lamps that provide similar light levels with improved optics at only 10W each. So if you have 40 linear feet of cable track zig-zagging over a public gathering area, you easily position 3 or even 6 lamps per 10′ section, whereas with 50W halogen lamps, each 10′ section would get only one or two lamps every 10′ section.
Have LED lamps come of age?

Full-bright in a non-dimmed clip-lamp, these new LED lamps provide bright light. The fact that there’s a hint of glare at an oblique angle to the lamp axis is unfortunate in this installation but a great achievement in LED technology, generally. The LA/LED series lamps may turn out to be an outstanding lamp for recessed lighting applications.
Based on my 8 hours’ experience with it to date, the latest generation of LED lamps may be ‘good but not great’ (as CFL’s have been for more than two years, now). For under $10/lamp, it appears I have my hands on a 50,000-hour lamp with good domestic-use (warm) color temperature and adequate light output from a standard, 120V, A19 lamp base. The lamp claims to be dimmable but that’s a qualified ‘sort of’ based on my initial testing (see below).
This morning, I purchased (12) of a Utilitch Pro 7.5W dimmable, 3000K, 40W-equivalent LED lamp, Model number LA19DM/LED
