Grote 7633?

[Crownfire]

Just saw this listed on eBay. I’m sure we’re all familiar with the 7620 and 7622 beacons, and their bigger cousin the 7624. This is a 7633. I was expecting a 3-bulb version (which I’ve never seen before) but it’s 12 volts and it has the same two bulbs as 7622. Does anyone know what different about a 7633?

@Skulldigger found a listing that indicates the difference is in the lens material:

This is a really old post that I found doing a search for Grote. Anyone figure out the difference in a 7622 and 7633? According to this ad it is the makeup of the dome. Acrylic is standard and the 7633 is Polycarbonate.

In fact, a copy of the 76333 product page, from before it was discontinued, is archived here:

https://web.archive.org/web/20160930201224/http://www.grote.com/products/76333-two-sealed-beam-roto-beacon-yellow-w-polycarbonate-lens

The only meaningful difference in that product page versus the current 76223 product page is the information that the 76333 has a polycarbonate lens.

Well that answers that. Thank you.
