SRC Member Tanzy Posted November 13, 2002 SRC Member Share Posted November 13, 2002 I'm interested in 400W Radiums. I thought all Osram Radiums are 20000K. If the price is reasonable, I don't mind getting a few. Quote Warning: Heavy handed moderator in operation. Threads and post are liable to be deleted or moved without prior notification.

SRC Member Phang Posted November 13, 2002 SRC Member Share Posted November 13, 2002 How much does a standard ballast for a 400W Radium cost???? Quote Link to comment Share on other sites More sharing options...
SRC Member Tanzy Posted November 13, 2002 SRC Member Share Posted November 13, 2002 I have no idea. They are suppose to be very blue bulbs but give an excellent colour combi with Iwasaki 6500K. When the 400W is used alone in US, it is always overdriven with a 430W Ballast or the 400W Blueline e-ballast. Any other ballasts runs it at the normal temperature causing it to be too blue to be used on its own. Quote Warning: Heavy handed moderator in operation.

SRC Member Phang Posted November 13, 2002 SRC Member Share Posted November 13, 2002 Thanks Tanzy... excellent colour combination with both Iwasakis and Radiums.....hmmmm Robe , Can I have the address of the shop where you bought the ballast?? Can a standard ballast with ignitor run a Iwasaki?? Quote Link to comment Share on other sites More sharing options...
SRC Member wsiong Posted November 13, 2002 SRC Member Share Posted November 13, 2002 I hope it is not too much to ask but can someone list down the specifications of the MH equipment/combination for easier reference? Example: Brand, Wattage, K, Colour spectrum, E-ballast, Ignitor etc Quote Link to comment Share on other sites More sharing options...
SRC Member Tanzy Posted November 13, 2002 SRC Member Share Posted November 13, 2002 You should be able to find all the required info at Metal Halide Lighting Component.

SRC Member alvy Posted November 13, 2002 SRC Member Share Posted November 13, 2002 Robe: Hi, got a question to ask a lighting expert like you: Can you install the mh bulbs side by side or together in the same reflector?? say a 250w 6500k iwasaki with a 250w 20kk radium?? Will the output be a blend of the blue and yellow or should the lights be totally separated, becoz i dun really light distinct rays of light (blue and yellow) in separate zones ..ie one side blue, one side yellow.

Morgan Posted November 13, 2002 Share Posted November 13, 2002 Does iwasaki bring in 250W 20K bulb? Quote Link to comment Share on other sites More sharing options...
Achilles Tang Posted November 14, 2002 Share Posted November 14, 2002 You guys may want to bring in the Spiderlight reflector, it will increase the efficiency of your MHs by a lot! Check out the review on it here. Quote Link to comment Share on other sites More sharing options...
Achilles Tang Posted November 14, 2002 Share Posted November 14, 2002 Another article on HQI vs single-ended bulbs of the same wattage... and the importance of reflectors for single-ended to match an equal HQI. here Quote Link to comment Share on other sites More sharing options...
SRC Member Phang Posted November 14, 2002 SRC Member Share Posted November 14, 2002 Cool... Spiderlight reflectors.... How much are they retailing it for.... and anyone interested???

SRC Member Tanzy Posted November 14, 2002 SRC Member Share Posted November 14, 2002 You are confusing me, I've only heard of 6500K and 50000K Iwasaki for use in aquarium. Do they have a 20000K?

Don't patronise Ushio bulbs! Quote Link to comment Share on other sites More sharing options...
SRC Member Phang Posted November 21, 2002 SRC Member Share Posted November 21, 2002 Hi Guys, Jus recently obtained 2 x Iwasakis to be mounted onto canopy... However a question, would it be neccessary to mount a piece of tempered glass between the surface of water and lights... My Canopy would be 13.5 inches from water surface... estimate that the lights would take not more than 5 inches from the top... so estimate a 8-9 inches gap between lights and water.... Anyone here use MHs without protective glass??? Saw those canopies made by reefers in US... don't seem to have any protective glass beyween water and MH lights....

Achilles Tang Posted November 21, 2002 Share Posted November 21, 2002 Unless you are using HID lights... then you need to get a protective glass that screens out excessive UV. The iwasakis and radiums bulbs are encased in a glass bulb which are coated with anti-UV already.... so in two words: NO NEED! Quote Link to comment Share on other sites More sharing options...
rrrobt Posted November 21, 2002 Share Posted November 21, 2002 you dont have to use glass for single end bulb and my is about 8-9 inch above the water too. Quote Link to comment Share on other sites More sharing options...

The iwasakis and radiums bulbs are encased in a glass bulb which are coated with anti-UV already.... so in two words: NO NEED! Actually, my concern is more to water splashing onto the bulbs when it is fully functional.... Think glass would crack or blow if there's any contact... Quote Link to comment Share on other sites More sharing options...
SRC Member Tanzy Posted November 21, 2002 SRC Member Share Posted November 21, 2002 Most definitely will blow if sufficient water get's splashed on, but salt spray won't hurt the bulb except to decrease the light reaching the tank. 8-9" is high enough to allow you to not use glass, but you will have to clean salt spray off the bulb and reflector weekly. I use glass because I realise wiping the glass is ten times easier than unscrewing the bulb and cleaning the reflector. Polished aluminium will be scratched and corroded too.
