Doing the same exact thing over and over again gets boring.  And so no mouse trap is ever good enough. My friend Brad Cooper suggested the use of "full spectrum" diodes to get a better PAR reading.  I intentionally don't measure PAR because the effect I'm going for is an overall light quality that is nice to look at, even if it doesn't  grow some plants as well as PAR optimized light sources.All of my experiments in light have shown that the best PAR readings tend to come from light sources that are not the best for human eyes.  I...

It's taken awhile to finally get this announcement out.  It's good news and bad news. I've been doing a lot of tinkering, as always.  The bad news is that I should have had these new design tweaks and features right from day one. The good news is that the large diodes (10w, 20w, 30w and 50w) are now mounted on a "plug and play" heatsink/fan unit, which makes the entire system removable should any issues arise.  It will literally take 10 seconds to replace a failing large diode, or even to go from a 20w unit to a 50w. This...

Anyone with a tall vivarium (I define that as anything 36" or higher) knows that getting enough light down to the bottom involves some issues.  A powerful light(s) is needed, which of course is going to produce a lot of heat.  So now we've got to deal with fans and that also can create unwanted noise. Fans also have a limited lifespan. I've been using this heatsink with a built in fan that is generally very quiet to cool down 10, 20, 30 and 50 watt large diode LED chips.  It generally works quite well, but there's no guarantee that...

This is a one of a kind custom built light that is actually a hood because it was designed to fit over the top of an entire viv, covering the mistking nozzles and tubing.  It should sit right on top of the glass. A client ordered this for a very large custom built viv, but strangely decided within a couple of weeks that the twin 20w spotlights were not powerful enough over the top of a 36" tall tank.  Since I run many setups here that are almost identical, I know for a fact that this is plenty of light...

Here's some things to think about when choosing a light size for your vivarium. In general you want to use/cover as much of the top of the tank as you can with the light panel so that the light is spread out over a wider area.   Because the various niches in the glass box hobbies all have different approaches to vents and misters, front or top opening, glass tops or screen tops, a lot of variables are in play. So what you need to imagine is the maximum usable space you have available to sit the light on the top...
