Growers of all levels have tons of questions. We answer the most often asked here.
Look in our Education Section for more detailed information about horticultural lighting.
HORTILUX™ lamps are manufactured in the US and have a brown monogram that changes to orange after approximately ten hours of use. This includes HPS lamps. More information on our monograms is available.
All electronic/digital ballasts should be able to run EYE HORTILUX grow lamps. All our grow lamps are manufactured to operate within approved electrical standards set by the lighting industry for HID lamps. The ballast provides the power to the lamp and should be manufactured to supply the proper voltage requirements set by the lighting industry. It is the ballast’s job to run the lamp, not the job of the lamp to be run on a particular ballast. EYE HORTILUX electronic/digital ballasts can operate HID lamps of any brand without issue.
Knowing the amount of light you need is best determined by the amount of space you are planning to grow in. A good rule of thumb is to have anywhere from 40 to 60 watts per square foot. Keep in mind the type of reflector you use will also help determine how much light coverage you have.
Each EYE HORTILUX grow lamp has a replacement guide on the packaging for reference. At the very least, single ended lamps should be replaced every 12 months. Double ended lamps should be replaced at least every 12-16 months.
All EYE HORTILUX grow lamps have a 1 Year Warranty from the date of purchase. If there is an issue and you would like to make a warranty claim return it to the retail store where the lamp was purchased. They will be able to test the lamp and issue you a new lamp. Make sure to have your receipt.
It depends on the lamp type. HPS lamps can be operated in an open reflector. A majority of Metal Halide lamps are required to be operated in an enclosed reflector. However, there are Metal Halide lamps that are rated for open fixture use. This rating is stated on our packaging and on our web site for reference.
There are no issues if you touch a Single Ended HID lamp with your bare hands. The glass used for SE lamps is regular, borosilicate and cannot be damaged by your hands. Double Ended lamps can devitrify (degrade) over time if you touch their glass with your bare hands. The glass used in DE lamps is made of quartz and the oil from your hands can damage it over time.
There can literally be hundreds of reasons why your grow lamp will not start. Make sure to double check the following…
HID lamps are not required to be UL listed by the Federal Government. Furthermore ANSI (American National Standards Institute) does not require lamps to be listed. HID lamps are considered a light source and therefore are not required to be UL listed.
