Green LED taxi lights are far too bright at DEN; in this specific case; Taxiway CN by 7W nearing Mike Taxiway. The lights are so bright it floods the cockpit and blinds the Crew making it impossible to see beyond the lights right in front of you. This same thing happens on the runway centerline LEDs at DEN and other cities; far too bright. Reduce brightness or go back to old-fashioned lighting. Green LED taxi lighting [is] extremely bright causing windscreen visibility problem.
The reporter stated that LED intensity did not appear consistent because; while all the lights are very bright; some appear brighter viewed on straight segments; but others are brighter in turns. The LED section on 7E at Mike is dimmer than some other lights when viewed straight on. The reporter did ask ATC about the brightness and was told the LEDs are not adjustable. The reporter did also compare these LED to ABQ's lights which have recently been upgraded and some lights are now adjustable. The DEN lights should be also; they are a safety issue.
An Air Carrier pilot reported the DEN green LED taxiway and white LED runway centerline lights are too bright and create visual interference which prevent pilots from seeing beyond the non dimmable lights.
