The gu10 bulbs are not bad, fun DIY project. I had them for three months but didnt like the look. I re-config the bulbs and use them for my planted tank. I also have the Taotronics led that Frank mention. It is comparable to my 5bulb t5 in overall tank coverage. Good polyp extensions on SPS and LPS, BTA loves it. It is no where near the AI Sol or Radion LEDs.
thanks
when u say no where near the AI or Radion, do u mean angular coverage or intensity
thanks!
