We mainly use and sell EIKO Brand bulbs however we do reserve the right to substitute other quality bulbs such as OSRAM, USHIO, PHILLIPS, etc., that will work in your application as good as the EIKO Brand we have pictured and advertise.  We stand behind the quality of the bulbs we sell.  We usually ship the next business day after payment is received.  Shipping will be by USPS Priority Mail and will include delivery confirmation.  The shipping cost is $6.75 to US addresses.  We do combine bulb orders to save on the shipping.  You will receive free shipping on multiple bulb orders that equal $150.00 or more (US addresses only).  International buyers are welcome but please wait for your invoice as the shipping may differ from the US addresses.  Thank you for looking.
