    If they have got the tech to make T8's, the T5's can't be to far behind.

    1400 lumens is high for such a low wattage unit, I would even consider running T8's as this is close to the T5 80watts output.

    T5 or 8 makes no difference whatsoever with led lighting.
    The Lumens only really relevant with the light in the 520nm band for your corals and if you remorgage your house you can have just that!
    the other problem is most leds come with a focal angle of bet 12 and 22 deg which means u will have a spotlight effect. there are 55 deg 3 watt leds but they are S**t expensive.
    I have built severall small led units but the cost is heavy.
