Ebay MH bulbs

I have used them for about 18 months now and the only thing that I dont like is they seem to lose their color a bit sooner than some of the other bulbs Ive used. But for 20 bucks I just change them when they start looking a bit too white. Also Im using the 20k 250 watt single ended plusrite bulbs.

how often do you change the bulb and what ballast do you use?
thanks
 
Just thought I would add that those who have had issues with these specific bulbs should post their comments. It is useless for you to say "don't buy these because they are cheap and lighting isn't a place to go cheap" if you have not even used them. Plenty of people have been using them and showing pics of their tanks and things are going very well for them. If you have an opinion, back it up with something more than "pricier is better", as that is what cmpanies who charge you an arm and a leg for anything WANT you to think.
 
I think I'm going to go with 3 x 250w 20ks DE for the blue look.

Do you run actinics as well? I pulled my DE 250 20K and put the 14K back in. Without running my 4-65 watt PC actinics the light is to "yellow/white" for me but with the actinics on its perfect-for my taste, I put the 14K back in for growth but if I did not have the actinics I would have stuck with the 20K.

Its been a few months I will get par readings and see how they are. At 1st I was getting readings of 400 at the bottom of the tank-22 Inches from the bottom of my fixture, over 800 3 inches below the surface-FYI

I wasn't planning on running any actinics. I am hoping with the 3 20ks I won't need to run any additional bulbs to achieve the color I am looking for. I will play around with it though when they arrive and see what the tank looks like color wise.
 
How much blue is in the 14K Plusrite. is it a definite blue color or more of a crisp white with a tint of blue.

I would say it is a little more white than blue but really not much. You really can tell that it is nit just white. I guess I am trying to say that they are not SO blue that the entire room has a blue hue to it.
 
Yes I have.


I have the 250 Watt DE HQI Bulbs on my 180. I've got 3x250 watt.

The picture is very large, but I'll post it here for you.

Does anyone know what is going on with Light Spectrum Enterprise (trust_deals)? I ordered 3 x 250w 20ks and a UV bulb on 11/19 and have yet to receive anything other than an automated invoice after purchase and no shipping info whatsoever. I have emailed the customer service and called but I can not reach anyone there. Anyone have any info on what their deal is?
 
Since it's been requested more than a few times, and I have both 14k and 20k Plusrite bulbs, I just put together a comparison photo. My tank is a 75g with dual 175w magnetic ballast mogul style MHs. As far as appearance goes, the 20k are much better in my opinion, and the opinion of the few people that have also witnessed them here in person side by side.

These photos were taken with no ambient light, just the tank lights in an otherwise dark room. The camera settings are identical for both pics, as was the tripod setting. The photos are unedited aside from cropping and combining them. The 20k bulbs are around 2 months old, and the 14k's are around the same.




anyway, here is the pic. I don't have a par meter, but to my peepers the 20k bulbs are a bit brighter overall. The photo loses some of the glow the tank has in person obviously, but it is pretty close to accurate as far as the general color goes... though the 14k is not quite so yellow looking in person

Do I think they are good bulbs? Absolutely. growth is good even on the 20k, color is very good... I have no complaints, I did have one show up broken, they sent me a replacement immediately after i sent them a pic of the broken bulb. Shipping was fast... 100% satisfaction, I see no reason anyone would need an 80$ bulb. I stocked up on them :)

Did you order them through trust deals on ebay? Still haven't heard from them about my bulbs. Do you have a contact number?
