Casio Projector Range

Short Throw Series

New Casio LED lampless

technology re-invigorates classroom

learning and dramatically reduces

cost of ownership for education.

United Learning offers best advice

on provision of a quality infrastructure

to 30,000 schoolchildren across

the UK. To this end, United

Learning Technologies group ethos

is to train and facilitate their 2,500

teachers to enable the most out of

new technology to positively enrich

the classroom experience.

Learning Technoloiges Team Leader

Geoff Gould has been an ongoing

advocate of deployment of worthy

audio visual equipment technology to

education establishments for over ten

years. He takes up the story. “Since

1999 we have had a policy of having

LCD projectors to accompany our

Interactive Whiteboards. However,

whilst LCD projectors were still a mile

ahead of the previous OHP projection

technology, distinct quality issues

were becoming apparent after just a

year or so of use.”

In the classroom, lamp lumen

degradation was the ﬁrst to go;

with lamps starting to signiﬁcantly

dim after 15-18 months of use.

In addition, ongoing maintenance

was required with ﬁlter cleaning

recommended on a monthly basis.

Ongoing lamp replenishment was

another constant drain. With most

schools holding a variety of LCD

projectors all with varying lamp

types, academies were required to

keep a rolling stock of replacement

lamps on premises.

Environmental factors within the

classroom itself also needed to be

considered when using the LCD

projectors. Blinds to divert natural

daylight often needed to be darkout

or even blackout quality and lights had

to be switched off to stop incumbent

light pollution. Teachers were also

concerned that these conditions were

less than ideal for those pupils who

may have been susceptible to eye

strain.

Teachers, school AV Teams and

IT departments turned to the

experts at United Learning for

advice, despondent that even

after just the second year of use

the LCD projectors were becoming

sub-optimal.

United Learning contacted their AV

partner, IDNS, who suggested that

lampfree LED technology should be

evaluated as an alternative technology.

Casio’s new XJ range was suggested

and following a demonstration, Geoff

and the Team at United Learning were

impressed by the immediate light

vibrancy on offer.

Communications to all of the United

Learning’s Network Managers followed

containing recommendations as to

why individual establishments would

beneﬁt, with proof points provided by

Swindon Academy.

A year down the line, the Casio

XJ LED projector ranges are

ﬁrmly entrenched across the UK’s

classrooms, with over 10 of United

Learning’s establishments running

the transforming Casio LED

projectors. That’s over 700 units,

with more being installed as budget

allow each week; their compact

size slotting into the existing ceiling

mounts and their inbuilt auto

conﬁguration quickly ﬁnding the

optimum viewing experience.

In terms of ROI vs. initial capital outlay

per unit, Geoff has conducted some

interesting ﬁndings with a ﬁve year cost

of ownership (TCO) plan for traditional

LCD vs. Casio’s LED projectors.

He comments on his ﬁndings: “A

traditional lamp based LCD projectors’

TCO over 5 years equates to around

£1200 (including projector, sourcing

& installing 1 replacement lamp,

arranging 1 offsite specialist deep clean

& ongoing onsite maintenance 6 times

a year); vs. Casio’s XJ unit that retails at

under £700 and simply has no further

overhead. It’s not just the ﬁnancial

considerations that stand out here.

It’s the fact that there is no downtime

or hassle factor with the Casio XJ

LED projectors.”

For total peace of mind, Geoff

notes that Casio uniquely back each

unit with a 5 year, 10,000 hour no-

quibble guarantee.

United Learning, nationwide advisor for 30,000 children across UK Academies’

& Independent Schools, recommends Casio’s Revolutionary LED Projector range:

“It’s not just the ﬁnancial considerations that stand

out here. It’s the fact that there is no downtime or

hassle factor with the Casio XJ LED projectors.”
