| Technology Comparison |
| LED vs. Incandescent Lamp |
| LED |
Incandescent Lamp |
Brightness and best visibility even in foggy
conditions |
50% brightness lost due to the lens cover |
| Consumes approximately 15W power |
Consumes 100W power |
| Life of over 10 years |
Life limited to 3-6 months |
Even failure of few LEDs will not completely
shut down the signal |
Failure of the bulb renders complete shut down
of the signal |
| No heat build-up in the housing |
High heat build-up and adds to failure rate |
No glare from daylight due to absence of
reflectors |
Misleads the drivers due to reflection of daylight
from the reflectors |
|
LED offered by TTI vs. LED of Others |
| LED by TTI |
LED by Others |
240VAC plug-in balls available for immediate
replacement in existing housings |
AC fittings not readily available, so widespread
use is very expensive and may not be feasible |
No need for Solar panel
|
Solar panel required. Dust / Snow accumulation
on the panels severely reduces the efficiency and consequent failure of the system. Not possible to
clean the panels periodically due to large number, high positioning and risk of damage |
| No need for batteries |
AC system obviates the need for Batteries |
As
retrofit is possible switchover to LED system
is less expensive |
Switch-over is expensive due to need for a
complete change of power supply |
