Iwasaki 6500k 400w users

Like to ask if your bulb has a "DL" on the glass envelope?

I still like my 6500k, inspite of the ugly yellow colour!

Reason?

The output of light in the photosynthetic range of the Iwasaki lamp is about 50 percent higher than the output of the 10,000 K Aqualine Buschke lamp, 75 percent higher than that of the 20,000 K Osram/Radium lamp and almost 100 percent higher than that of the 10,000 K Coralife lamp.

My SPS growth and colours are good!

Yah, but its sooooooo ugly

Radiums are better IMO

Me, but 250W version to reduce power bills. No problem to make SPS color up and growth is very good!

Ugly not really if you balance it a bit with 20kk lamps. It lasts longer too without a drastic drop in intensity.

Use them before.

In fact my very first MH bulb. (cos others won't available).

good growth but the yellow tinge sucks.

I would go for a BLV instead.
