SBMV lamps and all lamps above 60W probably became illegal in Israel for home « on: April 07, 2010, 06:54:37 AM » Author: dor123
I don't know what is happening, but an electrician that came to the hostel i live in at Lilenblom 13 st. Kiriat Ata to check electric things said me that i mustn't use my 160W SBMV lamp in my open fixture room and also any lightsource over 60W. I am guessing that the Israelis institute of standards ("INSI" or M.T.I) or even our the electricity government company decided, that all the installations of screwbase light sources over 60W at househole fixtures and sockets (Mainly incandescents and especially the SBMV lamps) are illegal in Israel. I think but i not sure, that this is for an electricity safety. But i am sure that this is not a ban or thing like this, although there is a massive move from incandescents to CLF lamps at homes and most commerical locations that previously uses incandescent lamps, much more i think then in USA.

Members, i made mistakes. most of the things that i wrote are mistakes. The electrician said me that that the electric wires from the ceiling to my ceiling fixture are exposed and there is a metal part attached to the plastic socket and also that the fixture is not grounded, so i can't use more then 60W. After the electrician will correct all the problem i will be able use my HWL 160W 225V SBMV lamps once again in the next winter.

Don't forget, then each socket has it's maximum rating (what does not exceed 75W for plastic ones) and your lamp was above such limit, so the inspector pointed correctly at 160W SBMV in "max 75W" fixture as fire hazard. For SBMV you should use fixture rated at or above the rated lamp power. When using discharges (except for SBMV), you should double the lamp rating to get required socket rating, as these lamps might increase their real power input (so the power dissipated to heat) close to their EOL, when operated at regular series choke ballast (because the socket has to be rated for the worst case maximum power during operation). So taking the "75W" plastic socket rating, you could not use more then 37.5W rated discharge lamp in it, while here is no E27 lamp below this level on the market, what mean for all discharges you have to use high temperature ceramic socket/fixture assembly. Furthermore for pulse-start lamps is good idea to use socket with 6kV electric strength even at elevated temperatures, what exclude plastic ones (for EU the required dielectric strength of power installation is 6kV, but it is tested at normal ambient temperatures) Further hazardous thing might be the use of "enclosed fixture only" rated lamp in an open fixture, but if i remember well, MV's (neither SBMV's) are not restricted for enclosed only, so i guess this was not the direst issue.

Medved: More correctly 60W max for plastic sockets. This limit as the electrician said me is because of the heat of the lamps (Not in case of CFLs) that heats the metal contacts in the socket and causes them to corrode. So until they don't replace the socket to a one that can have handle the heat of 160 SBMV lamp and have a max wattage rating more then 200W incandescent lamp, i will not be able to continue to use my Osram HWL 160W 225V SBMV lamp.

SeanB~1: Don't forget that the heat is also an issue and this is the main reason why plastic sockets don't rated to operates filament based lamps over 60W, as the ones above overheats the sockets and melt their inside or in rare case igniting them. The corrode on the metal contact (And indeed the contacts were completely browned) is more have to do with the current of the lamp but also with the heat as metals corrode more rapidly in very hot conditions. For all: Remember that my Osram HWL 160W 225V SBMV have much more heat then a filament lamps of a similar wattage range that my lamp have at all of its run-up states (150W and 200W filament lamps), as it is actually a hybrid light and heat source (Filamet with ~2300'K [Arctube warmed up] and arctube with 1000'C in the same lamp and an atmospheric pressure argon-nitrogen filling).

The issue with the heat is, then the incandescent emit nearly all of it's "heat output" as IR radiation, what leave the fixture without heating it up. But most other lamp types emit much larger portion of the "waste heat" as the convected heat (e.g. fluorescents nearly all of that), so warm up the fixture inside way more then incandescent lamp of the same wattage. This is big part of the the reason, why you (as rule-of-thumb) should not exceed the fixture wattage rating even with the "equivalent incandescent wattage" when retrofitting them. The other part of the reason is, they are way more sensitive to the generated heat then incandescents.

Yeah I've noticed new fixtures sold here now have wattage limit ratings for both incandescent and CFL lamps, the CFLs are equivalent in brightness to incandescent. By the way, the CFL adoption rate varies greatly across the USA. In northern California (around the greater San Francisco area) CFLs are everywhere, you may even see more of them lit up at night then incandescents!
