4 Feet Fluorescent 5000K

[jagemail]

I am looking for 4 feet long tubelights that give out true daylight output, these are typically rated for a color temperature of 5000,

5100 or 5500 degrees Kelvin.

I need them to build a lighting diffuser. Spend the last hour searching on the web without any luck. Any feedback?

Thanks

Hi

TLC do 5400K ones:-

or more likely candidates, but TLC don't provide enough technical info to be sure, but OP didn't give much info about what he wanted it for, so it's difficult to know what properties of daylight they're after.

Hi,

I am after some tubes that give out "color temperature of 5000 degrees Kelvin". I need them for a photo studio that I am setting up. Nedless to say on the cheap.... I did find

seems a bit expensive. thanks for links to tlc-direct but like you say there is not enough information there.

Thanks op

You may be interested in the following? I haven't tried them myself, but considering. About £15. If so do a Google search Information about Ecozone Biobulb Full Spectrum 100W bulb - bayonet

Lasts up to 10 000 hours, or seven years, giving massive energy savings to the user.

Technical Information: Flicker free, and radiates the full spectrum (380-780mm), Colour rendering index of 85, Light output of 1750 Lumens, Low heat 6500 kelvin colour temperature.

One hour spent in the presence of two 100 watt bulbs gives the same benefits as a 3000 Lux light box.

Caution: Use only with 220-240 volts. Indoor fixtures must contain ventilation holes. not intended for use with dimming circuits.

Continuous spectrum tubes of a given colour temperature ain't cheap and you'll not find them in stock at the usual suppliers. You'll need to order them or go to a specialist.

Why does an elephant have 4 feet?

Because it would look daft with 6 inches!!

Sorry couldn't resist!

Hi

The last two digits of the 'colour number' are the colour temperature. So for example an 854 tube is a tri-phosphor tube with a colour temperature of 5400K. A 154 tube is a conventional tube again with a colour temperature of 5400K

The preceding digit is the colour rendering index divided by 10, with 8 being 80%-89%.
