To what depth can you test your underwater lights?

We have the facility to test our products to 800 bar (8000 metres).

Why would I need underwater lights in my fish farm and what is the benefit?

Underwater lighting slows down the maturation process, photo period manipulating the stock of fish to shift their breeding season. Basically the light will slow down maturation of the fish by causing them to think it is still daylight outside hence enabling them to be fed longer and grow in size. If lights were not used to photo-manipulate the fish then they would mature at a low weight and the meat would not be edible. Another benefit is that you can put the fish to sea at several times in the year instead of the normal spring time.

Why do I need underwater cameras in my fish farm?

Feeding the fish is one of the most costly parts of fish farming, underwater cameras enable you to monitor the feed and make sure it goes to the fish, and not lose pellets through the bottom of the net. The cameras are linked up to computers and / or monitors on land which means you can take control of the whole feed system from the shore base. It’s also advantageous in bad weather when you can’t get out to the farm, the fish are still getting fed and you can see what’s going on.

What effect does the use of light have upon the weight of the fish / fish mass?

According to our customers we believe there to be more than 10% difference in size/weight. Stirling University have conducted their own in-depth research to provide further evidence of growth patterns.

What is the Lumens output for your lights?

Please see our product datasheets for answers. Our Pisces 1000 Output is 90,000 lumens

What is the life-cycle for your lamps?

Please see our product datasheets for answers. Our Pisces 400 lamp life is rated at: 16000 hours typical N.B. This is a statistical value based on the number of operating hours at which 50% of the lamps originally started will still be operating

How many lights do I need per cage?

Number of lights depend on several factors; turbidity of water, size of cage, stock size, breed of fish. BGB Marine representatives will be happy to assess your requirements. Contact: 00 44 (0)1476 576280.

When do the lights need to be on?

It depends on the maturation cycle of your fish. BGB Marine representatives will be happy to assess your requirements. Contact: 00 44 (0)1476 576280

 If I smash the well glass accidentally will I loose all the internal components?

If the well glass is smashed then the only components needing to be replaced will be the lamp and obviously a new well glass. All control gear is sealed into the main body making it water resistant. We would recommend that you send the luminaire back in this situation so that we can fit the new well glass and pressure test the unit to make sure it is properly sealed.

How many volts do I need to run the lights?

We run at 230v into the pen rather than 600v. We believe this to be a safer and more economical way to use the lights.

Which luminaire should I use the Pisces 1000 or the Pisces 400?

Early scientific results when comparing these two lights against growth of fish shows that it is much better to have an even “blanket” spread of light through out the cage. We will always recommend that you use a larger quantity of 400W lights and spread them out so you can achieve a blanket of light.

What length of cable will be needed on the farm?

This depends on your particular requirement. Our standard length is 25 metres, however bespoke lengths can be purchased.

Can I run my light(s) out of water?

No. The lamp requires the presence of water to keep it cool.

What plug options are available for the Pisces 400 power cable topside?

The Pisces 400 power cable topside is supplied with a blue I.P 67 connector the industry standard; this allows easy connection into cage side boxes. However we can supply just bare tails or a connector of the customer’s choice

How do I connect the Pisces 400 luminaire to my power supply?

When connecting the luminaire to a power supply it is strongly recommended that you use a waterproof, cage side box, housing an RCBO or RCD; coupled with a miniature circuit breaker, this provides circuit protection and protection against electrical shock. This cage side box is normally hard wired to the generator / distribution board and the luminaire is connected to the cage side box via the short cable assembly and blue I.P 67 connector supplied with the luminaire. We can quote on any size of cage side box to protect the user and the lights, please provide us your requirements

I want to put lights on the hull of my yacht, but do not want to risk any damage or mess!

Certain yacht lights do not require hull penetration. Our Afterburner light can be attached to the transom by fasteners or by bonding.

What do I have to do if I need to replace a yacht light?

In the case of our SeaArc light, lamp replacement occupies only a few minutes and is carried out with the luminaire on deck. Lens cleaning and removal and fitting of luminaires may be effected from within the water, with the swimmer wearing a mask and snorkel. A ‘dummy’ connector, with float attached, is provided to secure the cable connector whilst the luminaire is detached.

What are the benefits of Xenon HID lights over conventional light sources such as halogen?

The benefits of Xenon HID lights over conventional light sources such as halogen are as follows:

Greater light output in addition to lower power consumption - our 35W Xenon HID lamp used in the Afterburner for example produces up to 3 times the lumens at the light source when compared to a 55W halogen bulb and 5 times the lumens of a 100W incandescent lamp.

Greater visibility - the Xenon HID light source is a much whiter light as it has a colour temperature a lot closer to that of daylight than a halogen light source does. That is why halogen light sources are yellow in colour.

Greater service life - our Xenon HID lamp will last 10 times as long as a halogen lamp.
