Comments: I bought two bulbs. One of them worked fine. The other glowed very weakly when I turned the lights on. I reinstalled the poor bulb and it wouldn't go on at all. There were burn marks on the bad bulb after it glowed weakly. I carefully followed the installation intructions and used gloves. Now for $100+ I have 1 light nice bulb and one paperweight. Sigh...

Comments: I have used the Hamilton Technologies or Current 14k hqi bulbs in the past and they provided a nice white/light blue color. I decided to try this Ushio bulb because of the great reviews and the retailer does not sell the other two brands.I installed the lamp last week and I noticed that my corals and my clam have responded very well to this lamp. I noticed that my zoos and other corals are showing better expansion. I'm not sure if this is due to the new lamp or just the spectrum that it emits. I'm not so happy with the color of this lamp. This 14k lamp has the color of the 10k bulb that I have in another tank. It appears that this lamp has far too much of the yellow in it.

Comments: These bulbs give off a beautiful color! Just what I was looking for. Not too blue, not too yellow. Just a crisp white light. With my actinics on the tank looks perfect!

Comments: Great bulb for the price! Good color and exceptional shimmer.

Comments: After researching bulbs to replace my two AQ 250 watts that came with Aqua Medic Ocean Light these seemed to be a logical choice. I am very pleased with the decision. These bulbs are far superior while costing less then the OE bulbs. The bulbs are producing incredible results. The color of the bulbs is a crisp white with blue undertones, not yellow at all. These are by far the brightest halides out there! If you keep corals with high light requirements and like a more natural look these are the bulbs for you.

Comments: Corals look great with this lighting. A little tough to change the bulb, extra tight fittings.

Comments: Just put the bulb in my fixture yesterday. So far so good, but they say it takes up to 2 weeks for the bulb to "burn-in".

Comments: Color: Consistently as advertised across all of the Ushio brand bulbs I have used over the years.
<br />
<br />Price: Unbeatable!
<br />
<br />Longevity: I have been replacing my DE bulbs every 12-18 months without a noticable change in color, though a change in intensity is noticed and expected when replacing an older bulb with a new one. To avoid shocking your tank's inhabitants, just acclimate the system by increasing the photoperiod over the course of a week when the new buld is installed (beginning with 4-6 hours of light and adding on an hour or so per day).
<br />
<br />All in all, great bang for your buck. I will continue to purchase these bulbs for my own tanks and recommend them to others.

Comments: I loved the service. It was easy to place my order. And it arrived in no time. Highly recommend.

Comments: Installed the 14000K Ushio DE two weeks ago the and very pleased. Great output and nice midrange in between the 10K & 20K. This is used along with 2-65W 50/50 compacts about 12" above a 50 gal. Hexagon. Corals are lovin it.

Comments: Had the bulb for about a month now and all is well. My corals seem quite happy with it. It has good intensity and color, although I would rate it more like a 12K light. Could use a touch more blue tint. Overall quite pleased with the bulb.

Comments: First time using this bulb in a magnetic ballast ( aqua medic) it's a white flat color pink and I say birds nest is now closer to a light purple, this bulb is white I had 19k ushio before this one, it gave a warmer color not yellow compare to mx10k!,that yellow!! Very interested to see the growth on my spas now

Comments: The vendor got the bulb out to me very fast and in perfect condition. the Bulb itself has great color and I will be replacing another one soon using the same vendor/item.

Comments: Since I replaced my 10k jbj bulb I can see more blue from the 14k. It also makes the sand look more white. The 10k gave more of a yellow light. Overall its looks better. A little blue with a crisp white. I placed it in a k-2 viper on a 12 gallon jbj nano dx.

Comments: I knew ahead of time that the bulb is a little white but after the burn in period (~100 hours) I am hoping it gets a little more blue.

Comments: I don't know if the light is defective or what. The color of my rock and water look kind of yellow now. I will not buy this light again. I don't recommend it at all.

Comments: I have had the bulb in for about 3 days now. It is extremely yellow. I replaced a 10000 k bulb and was expecting more blue.

Comments: Nice crisp color. Is more 12000k than 14000k but I already knew that.

Comments: It seems to be like a good bulb, but a little white for my taste. It seems like its not quite a 14K bulb, but its not yellow after it burns it. However when it first turns on its a disgusting yellow, but that goes away after the first minute.

Comments: I have heard nothing but good things abour Ushio bulbs, except for the 14k 150 watt double ended bulbs. The 14 K in my tank driven by HQI ballasts, throws off a yellow glow. I am hoping that after the 100 hours burn-in that it will be less yellow and more blue, but if not Im replacing them with Radium 20K's. I wish I could return them.

Comments: I absolutely love the Ushio 70w 14k bulb, it is crisp white with just a hint of blue. I installed this bulb in my K2 Viper and all my corals opened right up and look great

Comments: Quite a bit more yellow than I expected from a 14000K bulb; good intensity but won't be using this model again unless my corals disagree with my opinion and begin a growth spurt.

Comments: This lamp makes everything comes alive. Compare to what I had before, is like day and night.

Comments: I just purchased a 250W 14000K Ushio and was a little disappointed in the color of the bulb. It seemed to be a very crisp white light when ran off my ARO electronic blast.
<br />If your looking for a bulb with any sort of blue tint this bulb will be a disappointment. I will be switching to the Phoenix 14000 immediately for it's bluer spectrum.

Comments: The color is great. Had these before and my corals love it.

Comments: I have been running the bulb for 4 days at 12 hours/day. It does not seem to be as "blue" as my old 14,000k bulb and it was OLD...
<br />I read somewhere that they start to "burn-in" around 100 hours. I am hoping it blues up a little more or I may replace it.
<br />I can say that it is bright enough. I am not sure what the PAR ratings would be on this bulb but for the money it is ok.

Comments: I must say this bulb is great especially for the price for it. It burnt a little whiter then i expected initially, but after a burn in period it started to develop a blue color. Very happy with product.

Comments: For a 14K it is more crisp than other brands I've tried, it really doesn't have that prominent blue hue. It does represent good color rendition and I will stick with this brand when time to replace the bulb again.

Comments: Thanks so much for the prompt shipment! I couldn't have asked for a better product! Keep up the great work and i'll def. be using Marine Depot again in the near future and for all my aquarium needs.

Comments: This bulb added just the right amount blue, it is a soft blue as opposed to the stark white of a 10k bulb, very happy with this product.

Comments: The bulb itself is very good ad of high quality. However the bulb's electrodes were not designed exactly for my fixture and were slightly too wide, I attemped to force it into the socket, which caused the ceramic endpieces to break off. I had to reglue the endpieces back onto the bulb, but it did install good. My recommendation is to use a lubricant to lube the electrodes, press into place, and then dry with a hairdryer. Then switch on afterwards.

Comments: So far this bulb is working great. In terms of color its very slightly blue. Mostly white. I like it more then the 10k because it really brings out the greens in the tank. There is no yellow in this bulb...
