Looking for a Hamilton 250W 14k DE bulb

[tonggao]

My current 14k 250W Hamilton just burnt out after only 5 months of usage (6 hours a day) with an icecap electronic ballast. Shouldn't the bulb last longer than this?

Anyway, I just put on an 10k AB bulb, and do not like the color. So I probably will buy another 14k bulb before too long. Before going online to buy it, I thought I should ask here to see if anybody has some laying around that you are willing to sell. Thanks.

Yes the bulb should last longer, infact it should last WAAAAAAAAAY longer, now the useful life (ie that which stays within the color spectrum) is about 9-10 months for the bluer bulbs but the bulb itself should not have burnt out.

Btw another bulb you might want to take a peak at is the 12000k Reeflux bulb, I've had 14kK hams (abeit 175w) and the 12kK Reeflux and the 12kK is more a stand alone bulb, where as the 14kK was too blue for my tastes.

Thanks a lot Mike for the information. I thought the Hamilton was of poor quality when I first bought it (very thin metal connectors, visably sloppy worksmanship inside the bulb), unfortunately it proven to be true.

I was thinking about the feeflux 12k bulb also, but could find little information on it. How does the color look? Is it crispy enough without supplemental light? Is it close to a typical 14k bulb? How is the PAR?

Thanks again,

I deal with Hamilton almost weekly and when I was going to add more MH's to the store, my salesman from Hamilton told me that their bulbs tend to burn out faster when used with E ballasts. FWIW.

I use the Reeflux without any supplimental lighting where as with the hamiliton bulbs I used daylight fluorescents to bring them to white a bit.

Can't help about par because I don't have a meter and I don't think Sanjay has tested those bulbs yet.

Really, did he say how much faster?
Any reason?

 

[MorandiWine]

He did not mention a time, but I would assume that it would be all over the place because there are going to be differences with all things associated with the unit. One reason he gave me that seemed to make sence was that the E ballasts tend to send surges of power instead of a constant supply. Who knows?!
