how long is this lamp?

Personally i think that all Lamp Bans are idiotic,the idea of telling us we cant use this lamp type just cause its less efficent is highly communist in nature...really what good is it going to do?

same size as the 3ft T12 fluorescent Tube

the Thorn 140w SLI/H lamp has a different Design known as the 4-leaf clover arc tube the Thorn 200w SLI/H has the 5-leaf clover arc tube, however due to the awkward manufacturing Process they became discontinued by the early 1980's and Osram GEC then discontinued them by 1990 they have the crescent shape arc tube, as it was alot cheaper to manufacture the SOX lamp, which was also more Efficient than SLI/H example a 180w SOX runs at 245 volts, by 0.9 amps (thus wil operate on existing 135 SOX or 200w SOI/H Ballasts) also the light output was increased from 20000 Lumens to 31500 Lumens, and also saving 20 watts per lamp especially on a long Motorway where the savings are in the Kilowatts, also the costs of the lamp was reduced from about £70 GBP to £30 GBP (at 1998).


All the Best for 2011

The Osram NA/T 200w is the old 200w SOX which was later rerated to 180 watts

the 200w SLI/H measures 909mm x 38mm the same length as a 3ft Fluorescent Tube

All the Best
