10watt should be good for a tank that size.
Definitely. They are bright
, and punching down 16 inches or so will be no problem.
I would look up the longevity on the Jungle Dawns before pulling the trigger, though.
I've run a number of those (a half dozen or so?) and had one die pretty quick. Inside of a year, for sure. The others are still going like little champs - the oldest must be about 6 years old now? Youngest are at least 3 years old. They are well ventilated, and live in a fairly cool room, which probably helps. It's not much of a sample, but it's a decent anecdote.
The LED floodlights have given me similar service - the odd one will die super young (cheap really is cheap
, after all...) but the rest (about 8, I think) are running like champs. My oldest of those is only maybe 3 years old though - time will tell. So - not quite as good an anecdote. They're in the same room as the JDs.
Point is, you pay your money and you take your chances. All else being equal, I just like the LED floods more now, just because I don't have to mount a socket fixture for a screw-in (lower labor). The result is lower-profile too, by about 3 inches, so I can fit taller enclosures into the same rack opening space. But honestly, not all is equal
- I like the light quality and the light dispersion better from the LED floods than from the JDs, too. For my uses, anyway. More support for the floods...
In the event yours don't come with a plug (some are meant for hard-wiring) - just be aware that the Chinese use different colors for their wire insulation. Yellow, and green or blue, instead of white and black. If I remember correctly - it's been a while.
Anyway - hope this helps a little.
