| Optical | |||
| Lamp lumen output (Lumen) | 672.1 | 724.02 | >100 lm/Watt --- good saving in power consumption. >75 lm/Watt --- moderate saving in power consumption. <60 lm/Watt --- poor saving in power consumption. <50 lm/Watt --- No point in using the lamp. |
| Efficacy (Lumen/Watt) (Lm/w) | 43.25 | 103.43 | |
| LED make | - | Nichia | TOP Branded LED Manufacturers - Osram ,Nichia , LUMI LED's , CREE Branded - Assured Quality and Life. |
| No of LED's (Nos) | 30 | 42 | |
| LED Operated at (mA) | 149 | 46.7 | < 50% ------- less stress on
LED, High Life. < 75% ------- more stress on LED, moderate Life. < 100%------- Higher stress, Low life. |
| LED max rated current (mA) | 180 | 180 | |
| % of Max rated used (%) | 82.78 | 25.93 | |
| Color Temperature (Kelvin) | 5888 | 6257 | ~2700K - Warm White ~4000K - Neutral White ~5000K - Cool white ~6000K - Day Light. |
| Thermal | |||
| Solder point temperature raise @ 25°C ambient (°C) | 34.9 | 11.6 | LED Junction Temperature <
60° - Excellent Life
LED Junction Temperature <85°C - Good Life LED Junction Temperature > 100°C - Poor life not recommended. |
| Estimated Junction temperature raise @ 25°C ambient (°C) | 68.45 | 38.88 | |
| Estimated Junction temperature raise @ 35°C ambient (°C) | 78.45 | 48.88 | |
| Estimated Junction temperature raise @ 45°C ambient (°C) | 88.45 | 58.88 | |
| Electrical | |||
| Lamp power (Watts) | 13.80 | 5.7 | 55% of Power Saved compared to S brand 15W. |
| Electrical I/P power (Watts) | 15.54 | 7 | |
| Power Factor | 0.97 | 0.93 | > 0.9. |
| VA | 15.94 | 7.56 | |
| Ithd (%) | 20.83 | 26.22 | Ithd < 30%. |
| Vthd (%) | 3.85 | 4.29 | Vthd < 10%. |
| Efficiency (% ) | 88.79 | 82.00 | Minimum Efficiency > 80%. |
| Power supply PCB | Single side-FR4 | Double side- FR4 | Life of normal capacitor - 1000 hours at 85°C
High Life capacitor - 10000 hours at 105°C This factor causes lot of difference in life time of the power driver. |
| Capacitors | Single | Dual with Redundancy | |
| Line filter circuit | No | Yes | Line filter protects the power supply from Power Line Disturbances. |
| Driver short circuit protection | Yes | Yes | |
| Driver open circuit protection | Yes | Yes | |
| Driver I/P surge protection | ? |
Yes IEC 61000-4-5 |
Sudden Surges due to Lightening or electrical disturbances will damage the driver so driver should be immune towards these surges. |
| Driver transient protection | ? |
Yes IEC 61000-4-4 | Electrical transients damage the electronic components hence the design should ensure proper immunity. |
| Driver voltage dips and interruption protection | ? |
Yes IEC 61000-4-11 | Electrical Line fluctuations will cause the driver to malfunction so the driver should work well even in fluctuating power conditions. |
| Temperature raise in power supply compartment (°C) | 41 | 20 | < 25°C - Good
More the temperature raise more it degrades the life. |
| Mechanical | |||
| Luminaire Cover | Plastic | UV Stabilised Polycarbonate sheet | UV Stabilised ---- retains whitishness
hence better light output. Un Stabilised ---- turns yellowish/dirty white over period of time reducing light o/p. |
| Housing type | Sheet Metal | ABS Plastic | Sheet Metal - Possibility of rusting
and denting. ABS Plastic - No rust and dents more elegant. |
| Ingress Protection | ? | IP30 | IP Protected - no insect and dust entry
more clean and more light. Non IP - Possibility of dust and insect entry making it dirty and degrades light output . |
| Performance | |||
| Case temperature raise above ambient (heat sink) (°C) | 20.58 | 10.51 |
< 15°C - works well in Indian climatic conditions without degradation in light output.
<30°C - moderate performance in Indian climatic conditions with degradation in light output. >40°C - poor performance with higher degradation in light output. |
| 24 X 7 Operation | ? | Yes | |
| Operating Ambient temperature range (°C) | ? | 0 to 60 | |
| Warranty (years) | 2 | 5 | |
| Life (years) | ? | 10 | |
