Okay. So I see that one. Todd recommended the double one to me for the same size habitat you have. Wasn't sure if you did the 3 bulb then for the timer or for extra plant light?No,cutting was easy, used pruning shears. And that is a single bulb but I decided to upgrade and ordered this one - http://www.lightyourreptiles.com/odessy-ho-t5-24-quad-fixture-w-arcadia-6-bulb-3-x-daylight-bulbs-built-in-timer/.
