I recently received a question via the contact form on the web site looking for advice about Interactive Whiteboards. The question went something along the lines of: in my classroom I have a IWB and projector. When I switch it on, the picture is so faint that the children cannot really see what is on display. Any advice, tips or suggestions would be very welcome about how to improve our situation please? Here are some ideas as to why a projected image might be faint.
One possibility is that the projector bulb might be on its way out so it might simply need a new bulb. However, before doing that, it may be that the lamp settings are set too low. The ideal Lumens (measurement of light) for a projector bulb is 2000 Lumens for an Irish classroom as we tend to have more natural light than our UK friends. However, there was a craze a number of years ago of selling projectors with 1500 Lumens due to some perceived problem with children’s eyes getting damaged. So before buying a new bulb, check the projector’s menu options and see if the lamp’s settings allow you to increase the Lumens to a higher value. Other than that, check the model number and Google its name along with Lumens to find out. If it is less than 2000 Lumens you might need a new projector or a darker room!
Please feel free to ask us any questions through the contact form and we’ll be happy to help where we can.

Have the inside of your projector professionally cleaned of dust – makes a serious difference.
Yes, good advice!
