Really disappointed with this 1. Wanted to get this for a 24x18x24 tree frog terrarium. The 4 bulb set-up looked great, that way I could use 1 low uvb 25 & a daylite blue bulb on one side, and in the other 2, I could use a pair of the of night blue bulbs. Unfortunately, I noticed that the max recommended wattage is only 35. (For a fixture of this size, I would have thought it to be rated for at least 50w-75w) No problem for the low uvb bulbs as they're rated @ 13w, but that pretty much eliminates any and all of the other bulbs, the lowest of which is 75w. Overall, its a nice canopy. Just only plan on using it for low/med uvb and/or low lighting (35w bulbs or less) and having a secondary "pot lite" if you need a heating / night / stronger uva light.
