Description
0o Specifications SThe new T8-T5 fluorescent lamp convertor decreases energy consumption by up to 50% compared to a conventional T8 fluorescent lamp.
O
Z The T8 to T5 convertor has created a means that will allow for the installation I of the new T5 technology tubes to be applied to all types of T8 fixtures without any need for any internal modification to the T8 fixture itself. Just a simple removal of the external conventional starter is all that is needed. The T8 to D convertor is designed to bridge the 2inch gap between the T8 fixture and the tube by using a true one piece fully insulated design. This also has significant benefits in energy saving (in excess of no visible flicker, no noise and instant start.
0 Older style T8 fittings generally use magnetic (inductive) ballasts or electromagnetic ballasts to provide the kick start voltage for the fluorescent N tube to operate and then rapidly limits the lamp current to safely sustain the discharge.
Ballasts are designed to optimally operate a unique lamp type. Fluorescent ballasts are manufactured for three primary types of fluorescent lamps: preheat, rapid start, and instant start.
Preheat Operation Lamp electrodes are heated prior to initiating the discharge. A 'starter switch' closes, permitting a current to flow through each electrode. The starter switch rapidly cools down, opening the switch, and triggering the supply voltage across the arc tube, initiating the discharge. No auxiliary power is applied across the electrodes during operation.
Rapid Start Operation Lamp electrodes are heated prior to and during operation. The ballast transformers has two special secondary windings to provide the proper low voltage to the electrodes.
Instant Start Operation Lamp electrodes are not heated prior to operation. Ballasts for instant start lamps are designed to provide a relatively high starting voltage (with respect to preheat and rapid start lamps) to initiate the discharge across the unheated electrodes.
The magnetic ballast is a crude ac current regulator that makes noise, works poorly over temperature changes, and produces a flicking light. A magnetic ballast alters the voltage but not the frequency. The electromagnetic ballast is an improvement over the magnetic ballast as it works on a higher frequency producing less flicker and less noise.
One characteristic of iron-cored electromagnetic ballasts operating at 50 Hz, is the generation of audible noise and flicker. Noise can be increased by high temperatures, and it is amplified by certain luminaire designs.
Magnetic and electromagnetic ballasts also require the use of a starter to operate the lamp. The primary means of improving the efficiency of a fluorescent lamp-ballast system is to operate the lamp(s) at higher frequency.
00 The T8 to T5 convertor easily overcomes the issues of older style ballasts by O having an inbuilt fully electronic ballast that operates the tube at a much C higher frequency. This operating frequency is 40KHZ 2KHZ.
O The T8 to T5 convertor houses all the required electronics, therefore no Z electrician is required to insert the unit into the T8 fixture. This can be done by IDanyone capable of replacing a normal fluorescent tube.
The T8 to T5 convertor operating at a much higher frequency and utilizing a IDfully electronic ballast also meets the requirements for EMC (electromagnetic compliance). The convertor falls within the scope of the Australian mandated standard AS/NZS CISPR 15:2006 for conducted (continuous and intermittent) radio frequency disturbance and radiated radio frequency disturbance.
oO The T8 to T5 convertor housing all the necessary high frequency electronics is so versatile and multi- purpose that if one chooses it will allow the further C removal or bypassing of the original ballast inside the T8 fixture. This is not a necessary requirement just a further improvement on the efficiency of the luminaire and must be conducted by a qualified electrician.
Further removal of the existing T8 ballast will further increase energy savings in excess of
