--- donsbulbs is closed for vacation ---

For now, I highly recommend you try this bulb dealer:

email: bulbwork@bulbworks.com

(Bulbworks is located in New Jersey, USA)

First, let me explain to you that those hard to find bulbs you are searching for, are most likely rare, and if available anymore they will be very EXPENSIVE.

In your FIRST email contact with Bulbworks, make sure you tell them the bulb number (and everything else printed on the old bulb), the bulb voltage and wattage (if known), and everything else you know about the bulb you need. They have access to many more bulbs than what is listed on their website.

As a reminder, Bulbworks is not part of donsbulbs so they can not help you with anything related to donsbulbs. And, since I'm on vacation, Bulbworks does not have access to my inventory

Don's grand wisdom: When multiple bulbs are in a circuit; if one bulb burns out, you really should replace all bulbs at same time. This way all bulbs will look the same. Otherwise, mixing "used" bulbs with "new" bulbs (or mixing brands) will each look different (some will be dimmer, some a different shade of color.) For example, automobile headlights and tail-lights must always be replaced in pairs or they will look odd. And, when one bulb is at it's end of life, the other will be near it's end of life too. Keep good working "used" bulbs as emergency spares.

Although few specialty light bulbs and sockets are manufactured anymore, I have decent inventories of most types in stock, plus additional sources for nearly everything. All are guaranteed brand new, most being NOS (new old stock). Shelf life is forever.

Prices usually rise as inventory is sold off. Website updated daily to reflect current stock and prices. Click add to cart button above, and order at today's prices.

My inventory does NOT keep track of brands. Expect bulbs to perform same regardless of brand. Submit order only if you don't require specific brand. Read my general information.

I need your help! I try to provide free accurate bulb data and cross-referencing. If you have additional information or found errors, click here.

Thanks to you;  donsbulbs is the world's largest resource of bulb data and cross-referencing.

Thank you, Don Schnapp
