Fluorescent Tube For Kitchen Lighting-Confused By The Numbers!

Hi all,

Have just become a member and i am trying to make sense of the fluorescent tubes in our kitchen lighting. 

The current tubes show L36W/535. Not being able to go out and make a purchase due to my health i resort mostly to online shopping and i can only currently find, within my budget, a L36W/835.

May i ask what the latter numbers mean please, and could i use an 835?

I hope this question is acceptable and that i have posted in the correct area.

Thank you.

Tony

36 is the wattage of the lamp

35 is the colour of the lamp......it actually relates to the Colour temperature in degrees Kelvin

35 is WHITE

Diameter of tube is measured in 1/8ths of an inch!!! Seriously, not a lot of people know that!

t12 is 1.5 inch

T8 is 1 inch

T5 is 5/8"

Just saying

Thank you for the information.

I had expected to find the 'T' printed on the tube and hadn't realised how these things are described. Now i am aware that i need a T5 i should be able to find what i need.

Many thanks again.

personally, for a kitchen id go with 840 or 865 (cool white / daylight)

he needs a 5 Andy,

so it'd be a 540 or 565,

and, I'd agree, its a better colour light in a kitchen

the 8 in the colour code is the CRI, not the diameter (diamter is always Tx, as kerch says). tri-phosphor is 8xx, older halo whatever is 5xx, which is why he cant find any. so yes, an 835 / 840 / 865 will work in place of the 535

Thanks everyone.

I am learning more as the day goes on - proof in the old saying that you never stop learning.

I thought i would have to follow suit with the tube that was already in the fixture, hence the 535. But if an 835 that i know i can get will still be acceptable then all the better.

Thanks again.

and are your sure you need a T5? 36w is a T8 size, never seen one in T5

On the tube it says L36W/535. I am assuming this does mean T5?

no, like i said the 5 in the colour code refers to something else. measure the diamter. As kerch says, this is the size in 1/8, so if its 1 inch dia, its T8, if its 5/8 its T5. Its most likely a standard 36w T8 you need, like this http://www.discount-electrical.co.uk/product.php/6623/ft36840-cool-white-triphosphor-t8-fluorescent-tube-36w-g13-240v-1200mm-x-26mm

Thanks Andy. It was more confusing then than i was realising. I appreciate your additional explanation.

Tried that line with First Wife

Silent breakfast ensued

No offence

Ever wondered why a Par 38 lamp is so called?

Par........parabolic reflector

38? Yep, you guessed it......38. 1/8ths of an inch!

So.....answer me this

Ashley JBs....when we were allowed to use them willy nilly

601......6 terminals.....fairly logical

301 ......4 terminals

401.......3 terminals..........explain that one!

Just wondering
