eBay find, I bought a case of 24 of these bulbs, splitting with my friend funkybulb because I don't need 24 and I can't afford $80 for the whole case lol. I got the whole case here, every single bulb intact and working at arrival. The other 12 will go to funkybulb when he comes over. The Direct-Lite bulb here is a PS-30 (or PS-95 for the metric users here) general service incandescent lamp with an additional aluminum reflective coating applied to the inside of the bulb neck up to the max bulb diameter. I believe it was originally a Birdseye (they made lamps for a while, in Peabody MA USA) product, developed in the 1930s (I have a couple old Birdseye bulb like this Direct-Lite) and added to the Sylvania lineup when they bought the lamp business from Birdseye. In the old Sylvania catalogs I have gone through, they had an extensive line of Direct-Lite bulbs. The smallest was a 60w A-21, and from there it came in a large variety of wattages and bulb sizes all the way to 1000w. The 1000w Direct-Lite was a massive PS-60 bulb (10 inches diameter!), physically larger than a PS-52 clear or frost GLS lamp. The direct-lite bulbs were used in a variety of applications, such as brooder lights, downlights, etc etc. Sylvania made them well into the 80s and maybe the very early 90s. The case I got dates to 1982. Duro-test also made an equivalent called Brillant Reflector. GE and Westinghouse also made 150w and 200w versions, primarily for brooder light applications. When this 150w bulb is lit, it is very bright and the filament is actually placed down near the neck rather than being dead on center, for better optical control.
