Render row lights-leds

[jojo9]

Hi,
i'm not an expert in rendering but usually i get good results when rendering with Podium V2.6.
My only problem are rendering rows of lights. I get too much light using point lights on a very low intensity, or some neon effect using LEM's (light emitting materials)-unfortunately these lem's brake my renderings in a unpleasing way.
Little lights-leds, very close together in a row of 1 meter. Some hints ?
