İ bought a projector lamp from jasper tronics, the lamp was not phllips lamp as they advertise, the housing that comes with the lamp is very hard to install and after several attempts you finally installed the lamp and just after two weeks the projector turns off and it shows the lamp is bad. You call them and they say the problem is with the projector. But you explain to them you had no problem before that. But they insist it is your projector. To make sure your projector is not the problem, you buy another lamp from different company and you can see the difference,the housing fit perfectly and projector works without any problem. You call them back with the explanation that projector is working fine and that proves the lamp is bad. They ask you to send the lamp back to be tested. Then they send you another cheap lamp which is going to work another 2 weeks. Their lamps and housing are cheap even if they give you 10 years warranty, you are getting lamp that lasts two weeks and you have the same problem with second and third lamp. İt is not worth it, save yourself from the aggravation , trust me,it is not worth it.
