Guys,
I'm looking for lighting that is good for -25 deg C and 0 deg C application. Who are the better brands to recommend.

Hi Kevin,
24V bulbs are widely used, I know that Danfoss, makes speciat sterters for neon that will start at low temp.
I use 240V bulbs, in a housing IP65.
Chemi :)
Go to your local electrical wholesaler dont buy arctic rated lights at £££££'s instead buy the plastic twin tube fittings with the diffuser/cover that clips into place, these ARE rated for -25oC and a fraction of the price.
Any metal halide fixture with a low temperature ballast is good for cold storage rooms. The only challange is that they are slow starting even in heated warehouses. However, they run very economically.
Weve been using metal haide in freezers for years and they work great, we recently added motion sensors to the lighting and seems to workking so far, so when no one is in the room the lights go out
had lots of problems with tubes and control gear failing best to leave light on when in a low temp enviroment
saves on cost of replacing tube/ballasts/starters and also cost of labour which is constantly rising thus offsetting cost of energy
Hi:)
Seen Mercury vapour and Sodium fittings used in freezers, slow to start, but economic to run:)
Kind Regards. Andy:)

We use Either Philips or Zumtobel or Glamox fittings for temp upto -40 deg c.
Absolutely no problems. We have used over 4500 fittings uptill now
Hi , We have developed an IP65 L.E.D light fitting which is perfect for cold store and freezer lighting . No Maintenance for 50,000 hours and also each individual light fitting is fitted with a PIR control which allows the fitting to be switched off or dimmed to 10 percent at non occupancy . These fittings run at 35 watts fully on or 3 watts in the dimming mode. Also available as an emergency light with 3 hour battery back up .
Cheers Pete
Flourescent lighting has come along way... You might want to look in this direction
came across one install were they cut a square hole in roof panel,sealed it both sides with clear acrylic and sat the cheap mercury halide on top,easy to service and install

It is very import in lighting to consider the type of coldstore you are working on.
The light affect the color or aparence of the storaged goods.
Also if the worker need read or observe the steekers on the pallets
MH or flourecent are white color
Sodio and incandecent are warm colors

Hi Peter
we are constructing a new coldstorage and are interested in your light fitting. Our rooms are - 25 C, 10 rooms. Need lighting for alleys, blastfreezer rooms and processing/chiller rooms as well.
Could you give me the technical specs of your lights and a price offer to
michael.raeuber@royalcargo.com
We are in the Philippines, but have a subsidiary company in the UK which is in the transport business
best regards
Michael K Raeuber

NEDAP LUXON: INNOVATIVE e-HID LIGHTING FOR CONDITIONED AND COLD STORAGE WAREHOUSING
HID lighting is ideal for low temperature applications and its lumen output is not affected by the extreme temperatures as low as -28 degrees Celsius. The innovative Nedap Luxon electronic HID ballast offers a significant opportunity to introduce sustainable lighting for Cold Storage and Conditioned Warehousing. The Nedap Luxon e-HID ballast is 10% more energy efficient than outdated magnetic HID ballast units. Secondly, it is now possible to continuously dim and let the HID lamps operate between 50 and 100% of the standard lamp power. Less heath will be generated, which results in a double kick back for energy cost reductions.
Because the e-HID ballast will cause less blackening of the lamp arc tube, it results in a higher lumen/W yield throughout the lamp life. With more lumen output it is possible for retrofit projects to replace a typical 400W magnetic HID installation with a 250 or 320W Nedap Luxon luminaire. Another important feature of the new e-HID electronics is the extended lamp life up to a double life time. This reduces the maintenance costs and lamp waste.
Optional for the Nedap Luxon e-HID ballast is the build-in antenna function. It enables the system to operate as a wireless platform with every ballast unit connected to the Luxon Central Processing Unit. Lamps can be controlled one by one or can function in groups. With the wireless connectivity the lamp settings are easily managed from a computer and can follow any future floor reorganisation. Most importantly, all lamp data are gathered and processed. This creates a powerful Lighting Management software tool: lamp status, lamp failure report by e-mail, lamp operating hours, real time energy consumption and savings, carbon savings and more. From any location one or multiple lighting networks can be monitored. Preventive maintenance and re-lamping is possible when the lamp burning hours enter or exceed the maximum lamp operating hours defined.
The Luxon Central Processing Unit can be connected to a building management system and let the HID lighting groups be integrated with the order picking program. It means that lamps will be ignited only for those aisles where goods will be picked and handled. The Nedap Luxon e-HID solution is ideal for new high-bay installations and for lighting retrofits. Several Cold Storage installations in Europe already operate on this principle and have achieved significant energy savings of 30-65%. With a payback time of 1-2 years it almost becomes a no-brainer.

Interesting write up
It would be good to see the numbers about energy savings and payback. How did you get 30-65% and 1-2 years?Quote:

*additional savings due to less maintenance on relampingg
Depending on the building structure and lighting requirements there are significant reductions possible.
