  1. This is a leaf cutting I took on July 8th. It's finally showing the new plant above the surface on November 9th. Oh did I mention that was July 8th 2013, 16 months ago? I've never experienced that time scale before, I was getting close to emptying the pot contents in the bin. This species still keeps presenting me with extremes.

  2. Been there, done that. I would look elsewhere for an LED based replacement. I'm currently experimenting with the LED 'COB strips' like these... http://www.ebay.com/itm/10W-COB-LED-Strip-Light-Bulb-Lamp-White-12-24V-1000LM-for-DIY-200x10MM-Rectangle-/360934272481?pt=US_Light_Bulbs&var=&hash=item54095bede1 They seem to be working out well (3x10w in a 3 foot tank) but I have only been using them for a month or so! Provided that you can dissipate the heat then you can chain them together into whatever form you require. You will also need an appropriate 'driver' so take note of the typical forward voltage and current of the parts and stick with similar requirements for each component eg if you want to use 20W 'COB' then make them all 20W 'COB' That way you can buy an 'off the shelf' PSU. The ones I got needed about 12v/0.9A each (3 in series - 36V/0.9A) and I happened to have an appropriate 30W driver hanging around. To be honest I was not really looking at 'energy savings' or 'spectral enhancement' but control. Most (useful) lighting is 'on/off', LED can be controlled down to the last 'Lumen'.
