FAQ

Why are iProjectorLamp prices so competitive?

iProjectorLamp has been specializing in projector lamps for many years. We maintain long‑term, direct partnerships with leading global light source manufacturers such as Philips, Osram, Ushio, and Phoenix. By sourcing directly from the origin, we eliminate unnecessary middlemen and pass the cost savings directly to you.

In addition, we operate multiple offices and warehouses worldwide, including  (USA),  and  (China). This global logistics network significantly reduces shipping costs and ensures faster delivery to your doorstep.

We also do not outsource our customer service – all representatives are internally trained professionals dedicated to providing you with expert support.

Which lamp should I use for my projector? How do I confirm the model?

The correct lamp model depends on your specific projector. The easiest way to find out is:

  1. Check the model number on your projector body or in the user manual

  2. Check the part number on your old lamp module

Once you have this information, send it to our customer service team and we will match it precisely.

We supply lamps for over 7,500 projector models, covering all major brands including Epson, BenQ, Sony, Panasonic, ViewSonic, and many others.

Are your lamps genuine / original?

Yes – absolutely.

iProjectorLamp only sells 100% genuine, brand‑new original projector lamps. We never sell third‑party or aftermarket inferior lamps.

All our lamps are sourced directly from world‑class manufacturers including Philips, Osram, Ushio, and Phoenix. Each lamp you receive is factory‑fresh and authentic. Using counterfeit or low‑quality lamps may permanently damage your projector within minutes – a risk not worth taking.

Do the lamps come with the housing (module)?

Yes – the vast majority of iProjectorLamp products are supplied as complete lamp modules (housing + bulb) , ready for direct installation into your projector with no additional assembly required.

A few models are designed to be sold as bare bulbs without housing. Our product pages clearly indicate whether the housing is included. If you are unsure, please contact our customer service team for clarification.

How do I replace the lamp in my projector?

If you do not have extensive technical knowledge of projectors or electrical hardware, we strongly recommend sending the old lamp module to your local authorized service center for replacement.

If you choose to replace it yourself:

  1. Ensure the projector is unplugged and has cooled down for at least 1 hour

  2. Follow the replacement instructions in your user manual

  3. Never touch the glass surface of the bulb with bare fingers – the natural oils from your skin can create hot spots on the bulb, potentially causing overheating or even explosion

  4. Always handle the bulb using a cloth or tissue

What are the best tips for extending the life of my projector lamp?

The following practices can significantly extend lamp life:

  • Ensure proper ventilation: Do not operate the projector in an enclosed space without airflow – excessive heat shortens lamp life

  • Clean air filters regularly: Dust accumulation prevents effective cooling

  • Use Eco Mode: If your projector supports it, this is the most effective way to extend lamp life

  • Wait 5 minutes between power off and on: Avoid frequent rapid cycling

  • Avoid vibration during operation: The bulb is extremely fragile, especially during the cooling phase – never shake or vibrate the projector while running

  • Allow adequate cool‑down: Follow the cool‑down period specified in your user manual

How long is my warranty?

iProjectorLamp provides a 200‑day warranty on every lamp sold, starting from the date of purchase.

Certain products may come with extended warranty coverage – please refer to the specific product page for details.

How do I obtain a warranty replacement?

  1. Send an email to our customer service address stating that you are within the warranty period and requesting a replacement

  2. Our representative will send you a warranty claim form – please complete and return it via email

  3. You will then receive further instructions on the replacement process

Please note: For non‑defective returns, full refunds are available within 30 days of receipt; exchanges are available within 200 days of receipt. Returned lamps that are tested and found to have no defects may be subject to a restocking fee. Refunds will be issued to the original payment method.

I just installed my new lamp, but the "Replace Lamp" indicator is still on – what should I do?

This is normal. Most projectors require a manual reset of the lamp timer after installation.

Please refer to your projector user manual for the specific steps to reset the lamp timer (often found in the projector's menu under "Options" or "Service").

The procedure varies by brand and model – typically accessed via remote control or on‑unit buttons. If the issue persists after resetting, please contact our customer support team with your projector model number for further assistance.

Can I test my projector lamp with an AMP or OHM meter?

No – this will not work.

Projector lamps operate on fundamentally different principles from standard household electronics. They function by igniting ultra‑high‑pressure mercury vapor inside an arc tube. At the point where the mercury vapor is located, there is no conductive electrical material to measure.

Projector lamps use customized ballasts that ignite the lamp with a higher voltage during the ignition phase, then drop to a lower running voltage once the circuit is established. This complex operation cannot be tested with a simple multimeter.
