Critters of the Lembeh Strait | Episode 14/2014
In this latest video, check out the Nembrotha rutilans in the midst of eating a tunicate – it reminds us of drinking a milkshake through a straw! There’s also some spectacular footage of a Melibe papillosa – truly a strange nudibranch – and a frogfish waving its lure in the hopes of catching a meal.

This week’s video of Lembeh critter goodies features superb close-up footage of a broadclub cuttlefish mom delicately placing her eggs in a coral patch and a gorgeous pink paddleflap rhinopias just being its fabulous self. Also take a moment to appreciate the glimpses into the world of super-macro, difficult or impossible to see with the naked eye, such as a tiny commensal shrimp aerating its eggs and, right at the start of the video, the way a messmate pipefish’s camouflaged eyes move as it surveys its environment. If you love nudibranchs, there is something for you as well. Enjoy the Critters of the Lembeh Strait!

Critters of the Lembeh Strait | Episode 09/2014
Did you know the flamboyant cuttlefish sometimes turns the tips of its arms into enticing worm-like lures to attract prey? Watch the video carefully to witness the bizarre tricks of this intelligent and fearsome hunter. A baby painted frogfish racing across grains of sand that are like boulders to him, a sinuous free-swimming ribbon eel and a crimson-red tozeuma shrimp full of eggs also make appearances on the underwater stage this week!
Review: i-Torch Video Pro7 Light
The new i-Torch Video Pro7 light packs serious functionality into a very compact double O-ring sealed aluminum body. At the time of writing, it is the smallest and lightest 5,000-lumen LED underwater light on the market. There are five power settings for white light (100%, 80%, 60%, 40%, and 20%) as well as two power settings for red light (100% and 50%)—ideal for shooting shy subjects. There’s also an SOS mode.
A single mode button caters to the light’s various functions. Holding the button down for one second powers the light on at the default 100% white light. By pressing the button again, you can cycle through the following modes: 80% white, 60% white, 40% white, 20% white, 100% red, 50% red, and back to 100% white. Pressing the button for two seconds turns the light off. Holding the button down for three seconds (when the light is turned off) activates the SOS mode. Press it again and you’re back to 100% white. At 5,000 lumens, the Video Pro7’s maximum output rating is impressive, and it boasts a very even 120-degree beam angle (with no hotspots at all), which is excellent for shooting video.
Power comes from a supplied 50Whr rechargeable lithium battery. To charge the Video Pro7, you simply open the unit and connect the charger. The green light on the charger switches to red, indicating that charging is in progress; the indicator light switches back to green once the battery is fully charged. A completely empty battery takes about two-and-a-half hours to charge. Obviously, it’s a good idea to buy a spare battery (MSRP $270), so that you’re able to switch batteries between dives.
You can get a good idea of the amount of juice left in your battery from the indicator light ring that surrounds the mode button. This indicator glows green when the battery level is between 70% and 100%, yellow from 40% to 70%, red between 15% and 40%, and flashing red when the level is 15% and below.

Preparing the Video Pro7
Getting the Video Pro7 ready for action is very easy. Firstly, charge the battery before using it for the first time by unscrewing the back of the aluminum body and plugging in the charger cable. When it’s fully charged (charger light goes green), check the O-rings for dirt and hairs and screw the light back together. For my test dives, I used two lights, adding ball mounts to each of the YS mounts and attaching the lights to my camera.
The Video Pro7 in Use
Switching on for the first time underwater, I found that the Video Pro7 gave a very even light well-suited for shooting video as well as still images. The color of the light is a little cooler than that from a Sola, but it’s not too cold. The impressive output of the light was immediately noticeable. In fact, when shooting macro I sometimes found myself using a smaller aperture because it was brighter than I needed!
Great for shooting video, the light also proved to be very good for shooting still images. Below are a few of the stills I took while diving with the Video Pro7.
Flamboyant cuttlefish (Metasepia pfefferi) male (about 3cm). Canon 7D, Canon 60mm Macro USM, SubSee+10, 2x i-Torch Video Pro7. f/5.6, 1/640s, ISO160
Flamboyant cuttlefish just hatched (about 7mm). Canon 7D, Canon 60mm Macro USM, SubSee+10, 2x i-Torch Video Pro7. f/11, 1/160s, ISO160
Ornate ghost pipefish (Solenostomus paradoxus) (about 12cm). Canon 7D, Canon 60mm Macro USM, 2x i-Torch Video Pro7. f/5.6, 1/800s, ISO160
Phyllodesmium magnum (about 7cm). Canon 7D, Canon 60mm Macro USM, 2x i-Torch Video Pro7. f/5.6, 1/1000s, ISO160
Mimic octopus (Thaumoctopus mimicus) (mantle length about 10cm). Canon 7D, Canon 60mm Macro USM, 2x i-Torch Video Pro7. f/11, 1/125s, ISO160
As well as testing the Video Pro7’s prowess in capturing macro video, I also put the light through its paces with a fisheye lens and shooting wide-angle—and even here I was very pleased with the results.
The video below contains some sample footage shot with a Canon 7D with a Canon 60mm macro lens and 1x SubSee+10, and with a Tokina 10–17mm zoom fisheye and a 1.4x teleconverter, in a Subal housing and dual i-Torch Pro7.

Final Thoughts
The Video Pro7 is an exceptionally small and powerful video light that performs very well for a light in this price range. If you’re in the market for a compact and affordable photo/video light equipped with a hefty output, I would highly recommend the i-Torch Video Pro7.
