Q. What is your guarantee and return policy?
A. Our products are guaranteed to your satisfaction. We will issue a refund or replacement if any product is found to be defective within 45 days. Products returned through no fault of the Bulb and Battery center may be subject to a restocking charge.

Q. Is there a minimum order?
A. No, there is no minimum order; however some bulbs and batteries are packed in multiples, such as a 4/pack or 2/pack. These sealed packs cannot be broken to satisfy an order.

Q. Are there shipping charges?
A. All orders are subject to a 5.95 shipping charge. Battery orders may be charged actual freight. Freight charges may be waved for accounts that order regularly. Please sign in using your e-mail address and password to get your special pricing, terms and conditions.

Q. Will my credit card be charged if the order is on backorder?
A. Your credit card is charged at the time you place the order as it is assumed that all parts are in stock. If a part is out of stock, we will notify you within 24 hours (barring weekends or holidays) of the approximate time of delivery. If you decide to cancel that part of the order, or if the order will not be available for 30 days or more, your credit card will be credited for that amount.

Bulb related questions

Q. How long does an LCD bulb last?
A. LCD bulbs usually last any where between 1000 – 3000 hours. If you use it a couple of hours a day you will probably replace it every 2 years. LCD bulbs lose their intensity over time. Some manu-facturers claim that their bulbs will last 5000 to 6000 hours, but they are expecting you to use them at 20% or their original intensity. We recommend you change them when they reach 50% of their original intensity.

Q. How can I make an LCD bulb last longer?
A. It is very important that the lamp is cooled down properly after the projector is turned off. The average cost of a replacement bulb is around $300 each. A good UPS can be bought for under $100 and save you the life of the lamp should it be inadvertently unplugged or suffer a power outage.

Q. What is the difference between a Halogen and Incandescent bulb?
A. Incandescent bulbs have a carbon filament which darkens the glass envelope over time, last a few hundred hours and produce a warmer (more yellow) light. Halogen bulbs use a tungsten filament which does not darken the walls of the quartz/glass envelope because of the halogen process, lasts much longer, has a cooler (more blue) light and is exceptionally hot when turned on. Because these bulbs burn at such high temperatures we recommend they not be touched with your bare fingers. The oil from your fingers will boil on the quartz/glass envelope and cause an early failure. This is called devitrification

Q. Why are some bulbs identified with a three letter code?
A. This is called the ANSI (American national Standards Institute) code. The letters themselves, have no inherent meaning. The letters designate specific physical and electrical characteristics. This insures that you get the same bulb when ordering by this code, regardless of the manufacturer.

Battery related questions

Q. What is the difference between NiCad and NiMH batteries?
A. Some manufacturers specify either the NiCad or NiMH battery. Please heed their instructions. The main differences between NiMH and Nicad are:
1. NiMH has twice the energy density as a NiCad of similar size making them a more suitable for high drain applications such as video cameras, laptops and cell phones.
2. NIMH batteries are more environmentally friendly and can be disposed of in normal (except California) municipal waste.
3. NIMH batteries are less prone to "memory effect" that is typical in NiCad batteries. This allows NiMH to be recharged at any time without having to fully discharge the battery. It is recommended that even NiMH batteries be completely discharged once every 8 or 9 cycles.

Q. How many times can I recharge my battery?
A. Not all batteries can be recharged. Here are some general statistics for those that can:
NiMH batteries = over 300 times
NiCad batteries = over 500 times
Lithium Ion batteries = over 500 times
Sealed Lead Acid = over 200 times
