| Re: How to tell if a lamp is bad?
I believe the bulb life actually should follow the half life curve, so when it is rated at 2000hrs it would in theory be half the light output.
These bulbs actually lack a little Red out of the block, and over time this effect appears to worsen. My bulb is at 1100 hours, I did a calibration on it last Saturday night and light output is a struggle, what I really noticed was how far Red was reduced in certain standard modes.
Visually I noticed faces heading a little green and or pink at times, so as the bulb ages I also think one needs to tickle the adjustments, colour/tint more often.
This aside, you I believe did the right thing to send it back. Here though what they did is weird, to change those components and not change the bulb aswell is weird if the problem still exists. Although they said, replace the bulb, so why not just do that in the process?
Although you dont mention warranty at all, so I presume you had to pay for the service, if so why again didnt they change the bulb? If it was a warranty job, it is a difficult position for the customer as you have to trust the service people.
What is and what isnt causal can lead to arguments, there I believe the right thing to do would be replace the bulb for customer satisfaction. Even if it wasnt casual, proof is hard to establish, where as satisfaction and return business is assured if the product is returned working.
At this point I would buy a bulb, if it fixes the issue, great, move on.
If the problem continues, return it to the service agent and take the value of the bulb off the bill. Since it was their statement that it would fix the problem.
Light changes what it is doing depending if we are looking or not. Considering we only see this as a reflection of the past....what is it really doing now?  |
