12 lamps per case
Our most popular standard lamp configuration uses 60 Watt High Output T-12HO fluorescent lamps producing 4050 lumens per lamp (8100 lumens total). However, we do have options, including:
F54-T5/841/HO – 54 watt, 5000 lumens per bulb, 20,000 hours life, 4100 Kelvin color (Suffix –T5)
F48-T12/HO – 60 watt, 4050 lumens per bulb, 12,000 hours life, 4100 Kelvin color (Suffix –T12HO)
F32-T8/841 – 32 watt, 2950 lumens per bulb, 24,000 hours life, 4100 Kelvin color (Suffix –T8)
F48-T12-D-HO – 60 watt, 4050 lumens per bulb, 12,000 hours life, 5100 Kelvin color (76 CRI - Color Rendition) - This specialty lamp is designed to mimic daylight conditions. For paint spray booth operators requiring a brighter color light than a traditional "cool white", this bulb can be useful. (Suffix –T12DHO)
NOTE ON LAMPS: There is some confusion on T-12 bulbs. There are 2 types of T-12 bulbs. The older T-12 bulbs ran on magnetic ballasts. Those ballasts have vanished and the T-12 bulbs that work with those ballasts are vanishing as well. All of our explosion proof fluorescent fixtures use electronic ballasts and the F48-T12/HO bulb is widely available and low cost to replace. We use Philips bulbs and they plan to continue the T-12 series indefinitely, as does GE. In fact, GE is now selling an electronic ballast replacement for T12 based fixtures that formerly operated with their magnetic ballasts.
We offer a choice of bulbs with all of our explosion proof fluorescent fixtures. However, we standardize on the T-12HO bulbs mostly for their cold weather start capabilities and 60 watt high output. Many of our customers, including Naval bases, shipyards, oil rigs and petrochemical processing plants operate in very cold conditions, and T-12HO operate best in those environments. The T-12HO bulbs are also the least expensive to replace. T-8 bulbs are inexpensive as well, but you trade off lower light output for longer life. Finally, T-5 bulbs cost about 2 times that of the other bulbs but offer high light output and long life.
