Or even MV on reactor ballasts, anyone here know which ballast will make MV last the longest??

I do know MV CWA ballasts aren't very tolerable to dead or missing lamps, while HX reactors will last years with a dead or missing lamp. HX and reactor ballasts have fewer ballast losses as well I believe. I perfer HX and reactor ballasts over CWA.

They also don't tolerate shorted caps that well too so if I had a older CWA ballast with a non protected cap I would change the cap since if the cap blows or shorts the ballast will usually overheat.

Only time will tell when these LED bulbs would outlast the High Pressure Mercury Vapor bulb

I'm pretty sure that MV lamp, being made in the late 60's, will outlast the LED shown here. If it were a "Regent" mercury lamp - probably not.

I will say regent lamps are better then caster and Philips

Hmm out of Caster, Grandlite, Regent, Philips, Sylvania, GE, and Faux Westy whose current MV lamps are the best?

Sylvania mercs are the best of the current ones.

I agree with Dave, those Sylvanias are great lamps.

Ahh thanks, it looks like I made a good choice deciding to get a Sylvania for my yardlight.

Their color rendering is also alot better from what I've seen.

They Sylvania lamps are a bit pink with the /DX ones. The pink tone sorta annoys me inside, but my skin doesn't look green at all. In fact, it's ALMOST as good as a MH lamp, although MH has better CRI. I have a clear Sylvania 175w merc and it works great too. The only times I DON'T recommend Sylvania to people is about CMH, CFL and LED. Phillips is the best for CMH and LED IMO and CFL is horrid no matter what brand you buy.

I don't like MH lamps that much since they're way too white.

Too white? Don't you want white light? MH is definetly glarey so I perfer the coated lamps and I also perfer protected lamps as well.

MH lamps come in 3,000K in most wattages if being too "white" is a problem , i own a 150W phllips 3,000K coated non-protected probe start medium base lamp , its a cram lamp

I like white light, I just don't care for white white white light. I like metal halide lamps that have a color rendering similar to mercury vapor.

The CRI is to some extent a very relative characteristic. The colour temperature is in my opinion much more important, as the eye can adjust to a lack of certain colours, but cannot change the general appearance of the light. That's the reason why incandescents still exist today! Many people always preferred the soft light of an incandescent over fluorescents.

I perfer the MH lamps with more blue to them over the intense halogen color of the newer PSMH lamps.

Anyone here try the 4000K CMH lamps, I kinda like them over regular MH they're a pretty good match for /DX mercs imo.

This belongs in Lamp category, not Misc...moving it.
