Today, I as usual, went with my father to Mai-Wok asian restaurant in Hataasia street, at Nesher. This street is full of GE M250R2 drop lens cobraheads, most of them have 250W HPS lamps, but few are 250W mercury lamps. When we enter the street today, at a coincidence, the streetlighting turned on. Guess what: The mercury GE M250R2 glowed an intense 3000K halogen color light! (Instead of the usual dim pink or magenta color of a regular deluxe white mercury lamp) Initially, i thought that these are MH lamps generally (Most MH lamps also glows 3000K color when initially turned on, because of their electrodes glowing). However, their halogen color was much brighter than the initial color of the HPS lamps When they turned on, in fact too bright to be MH lamps. So i have discovered that these mercury M250R2, actually not contains mercury lamps, but SBMV lamps! (Yes, 250W E40 SBMV lamps) Unfortunately, my GP Recyko+ LSD NiMH AA batteries of my camera, became dead, as my camera refused to operate and displayed "Change the batteries", despite i charged then several days ago, so i have no pictures of one the M250R2 with the 250W SBMV turning on. And as we moving to a summer clock, i don't think that i will have a chance to see these lanterns turning on again. Hope that their SBMV will survive until the next chance.
This is unusual to see SBMV lamps is streetlighting. I only encountered a few such extreme example in my life: 1. In the very far past, in Givat Brenner local council, i saw in a main road SCHREDER DM 3 lanterns. Most of them, were HPS, but few of them were 250W E40 SBMV, that initially thought to be HPS that stuck in between mercury and sodium color, but turned out to be SBMV, when i saw them turning on (They later relamped to HPS lamps). 2. In The Meginim street in Haifa, i saw when i was a child, one old version of the Koffer 150, that had a 160W SBMV, when the streetlighting turned on (All of the lanterns in this area are today Philips Stradasole 530 with 150W HPS lamps). 3. When i was a child, and i was in Boris Milman center for autistic children, when this center was in its older place in the Parsim street, the building in front of it, had two floodlights: One Gaash Zohar with what i thought to be an 400W mercury lamp (Because of its elliptical coated shape and pinkish color when lit), and one farther Gaash Jupiter with a MH lamp. However, when i saw these two floodlights turned on, the mercury lamp in the Gaash Zohar, turned out to be a 500W E40 SBMV, as instead of a dim magenta or pink color, as usual from a yttrium vanadate coated mercury lamp, my eyes being blinded quite unexpectedly by an unusually intense, blindery bright 3000K halogen color light that came from the Gaash Zohar floodlight. 4. When I was in Yotvata In The City restaurant in the far past, near the lower station of Stella Maris cable railway and Bat Galim promenade, i saw the 400W lowbays of the station turning on. One of the lowbays had a HPS lamp, and the rest were mercury. One of the mercury lowbays, glowed an intense 3000K halogen color instead of the pink color of the rest of the mercury lowbays, indicating that it have a 500W E40 SBMV lamp. In all four example, i knew zero in lighting and i was a child or teen, despite this field already interested me, but as i remember these cases good, i know which lamps were in each fixture in each examples.
