SPARTAN Flood & Bulkhead
Product UpgradesÂ
Thorne & Derrick are pleased to announce that Raytec (world leaders in LED lighting for hazardous area environments) have recently made some upgrades to their SPARTAN Flood and Bulkhead products.
In the short article below Raytec explore some of the improvements in performance and efficacy of the SPARTAN hazardous area lighting range.
The introduction of the SPARTAN Mid Power Flood, combined with upgrades to the existing range, means Raytec now offer a comprehensive range of well-engineered, cost-effective floodlight solutions across a broad range of lumen outputs from 2,250 to 25,000 lumens.Â
SPARTAN FL Flood Upgrades
LED upgrades to the SPARTAN FL range, including the FL24 and FL48 Flood, have allowed us to increase the lumen output by an impressive 70%. Let’s compare the existing FL24 and FL48 products with the new updated versions, using the Zone 1 variants as an example;Â
Old | New | |
FL24 | 5,000lm / 68W | 8,450lm / 68W |
FL48 | 10,000lm / 136W | 16,900lm / 136W |
Efficacy | 74lm/W | 125lm/W |
70% improvement in lumen output and efficacy |
With these upgrades, the FL24 and FL48 Flood products will remain an important part of the SPARTAN portfolio; leading the floodlight range for emergency performance, as well as providing low voltage, extra low voltage, and DC solutions.Â
