Where can we learn about Data Projectors?
Where can we buy a Data Projector?
The CBI Project used
a Sanyo XU70 data projector (1500 lumens, XGA)
The Project also used the Hitachi EDX10 data projector (XGA, 1500 lumens) around RRP Euro 1300 (including VAT).

In the UK, BECTA had set a standard projector brightness of 1500 ansi lumens:
"Brightness of 1,500 ANSI lumens will be adequate for the majority of classrooms; for many smaller classrooms, 1,000 ANSI lumens will be sufficient. Therefore, the default search criteria used for the catalogue ranges from 1,000 to 1,500 lumens.
It is not possible to purchase different components of a complete whiteboard solution from different manufacturers, so the choice and branding of the projector will be based on the choice of whiteboard supplier and their projection equipment."
The Hitachi EDX10 and EDX12 have a brightness of 2000 ansi lumens, but they could be downgraded to run at 1600 - this extends bulb life, but more importantly the lower brighness helps reduce the glare which can be reflected from CBI screens. These projectors can be supplied in either an Orange or Grey casing: orange is used in some schools in order to make possible thefts much more obvious. A second bulb is also provided within 3 years or 2000 hours (whichever comes first)There are many suppliers of the Hitachi units, including Meritec (above)and Uptown (firstname.lastname@example.org)
As per the 'NCTE Projector Framwork Guidelines' (http://www.ncte.ie/purchasingframeworks/), you should now be looking at Short-Throw or Ultra-Short-Throw Porojectors ...a number of which also now come with their own in-bulit 'interactive pods' (which means they can be used with existing dry-erase boards)
