I tried this product on a nano planted tank. Its pure GARBAGE IMO. I really don't mean to rain on your parade, however, its just a bad product and you probably wont get any decent growth from it.
WontonSally is right about the CFLs from Walmart. I'm using 1 of the 26 watt (100w eq) over one of my vivs and it is getting the job done. However, these bulbs run considerably warmer. My vivarium temp is ~2-4 degrees cooler with the screw in LED I got from light your reptiles. If heat isn't a concern for you then the cheep CFLs will get the job done. For me, you cant beat the color and appearance of the LEDs.
Agree with this. Find room to stick in a 23-26W CFL and you're set to go. LED is a waste of money and I still believe is inefficient in terms of lumens per watt and even more so in terms of lumens per dollar.
It's not that LED is still immature as a lighting technology. It's more that it reached its limit. I'm sure there will be better solutions in terms of lumens per dollar in the future. It just won't be in the current LED technology.
At this point in time, indoor plant grow lighting is governed by the light intensity bracket you want to be in. For low to decent plant life sustaining, the most efficient way is fluorescent technology AKA CFL bulbs or high output T5 strips. But if you want higher lumens for top notch growth, you'll want to head into HID territory which isn't necessarily great on your animal life. In terms of terrariums, i believe HID isn't necessary unless it's for large enclosures in the realm of >48x48x48.
All small, mid reptile vivariums or planted terrariums should use fluorescents.
