I've had three tanks now and each time I saw anemic growth of my cheato. I tried many different lights (CPL 40 watts, 5000K 15 watts, LEDs, etc.) but these seem to cause very rapid growth. There is a halogen and a xenon version. I had three lights on my cheato but the moment I put one of these on it took off. They are small too. But they do run hot though.
