The Real 8to5 Story
In 2004 the 8to5 canister type energy saver was introduced by Mr
Penny Wong original proprietor of www. 8to5 lighting.com (no longer
available). The advantages of this design included low mass of raw
materials needed and easy packaging and transportation of high numbers.
The distinct rounded square shape of the 8to5 canister had a major
disadvantage, it would not fit many of the standard multiple lamp
(3 or 4 tubes) luminaires.
The shape was redesigned to a cylindrical shape so it would fit
a majority of luminaires; however the reduction of internal volume
created further over-heating problems because components needed
to be mounted much closer together.
A further 8to5 canister redesign included vents to the side of
the cylinder to aid component cooling during operation.
Unfortunately, particularly in United Kingdom, this 8to5 canister
unit would still not fit many of the common multiple lamp luminaires.
Installation was hazardous requiring both end of the 8to5 canister
units to be held and twisted in perfect synchronous direction. It
was soon realised that the replacement of the T5 tube when it reached
the end of its efficient life would be equally hazardous and possibly
dangerous if done by someone not properly trained. |
