Talk:Multifaceted reflector

message: This article doesn't mention at all why the reflectors are faceted instead of a smooth parabolic reflector. Is it possible for someone to describe the advantages of this arrangement? FletcherD (talk) 08:27, 2 November 2022 (UTC)
thread_title:  Why the facets? 

message: The article currently says:
:MR11 and MR8 lamps have pins placed more closely together, preventing them from accidentially being interchanged with MR16 lamps.
Brianpirie, are you sure about that? I'm almost certain I've operated MR11 lamps in a socket that was intended for MR16 lamps.

message: "The combination of the halogen light source and dichroic coating also means that these lamps provide a high color rendering index and a higher color temperature than standard incandescent bulbs."
higher CCT is due to the higher filament temp of halogen lamps. Halogens don't have higher CRI than non-halo filaments, both are apx 100. The dichroic coating doesnt have much effect on either, though if any effect, it can reduce CRI just a little.

message: The statement about never using dichroic lamps in recessed lighting appears to be an over-generalization:
:"Dichroic lamps, however must never be used in recessed lighting as they are a common ignition source for building fires."
Virtually all recessed fixtures sold in the U.S. have thermal protection (per the Underwriters Laboratories voluntary standards), and manufacturers have not restricted their MR16 recessed fixtures to non-dichroic lamps (e.g., Philips/Lightolier and Cooper Lighting/Halo). Additionally, the IEC 60598 labeling on MR16 packaging does not appear to be used in the U.S. Apparently that designation is for products sold elsewhere, such as Australia and EU countries.

message: The article says that the MR16 was first sold in 1965, but that those lamps weren't faceted. That implies that, if they were called "MR16" at the time that the "M" didn't mean "multifaceted", and that "MR" is a backronym. Or, that they were called something besides MR16s, and we should say what that was. Any idea which would be true? -- Dan Griscom (talk) 11:41, 29 June 2013 (UTC)
thread_title:  Is "Multifaceted Reflector" a [[backronym]]? 

message: From Design and construction:
"Halogen MR16 lamps consist of a halogen capsule (bulb) integrated with a pressed glass reflector. The reflector of an MR16 lamp is 2 inches (51 mm) in diameter. The base conforms to bi-pin GU5.3 standard."
This last part is incorrect, or at least, incomplete. Low-voltage (12 V) MR16 lamp bases have the GU5.3 bi-pin configuration, but mains-voltage MR16s have the GU10 twist-lock bi-pin configuration.

message: Under "operation" the article states:
"MR16 lamps are available in 10–50 W power ratings (150–800 lumens)."
Actually MR16 lamps are available to at least 300 watts as an ELH MR16 (rated at 300 watts at 120 volts), which has applications in stage and studio. The lamps were originally developed as projector lamps which had to have a high light output and consequently high wattage. See US patent #4021659.Tsadowski (talk) 16:58, 21 February 2014 (UTC)

... Note that this lamp was not "multifaceted"; faceted reflectors were introduced in 1971.
