**(a) Title of Class of Securities:**
Class A ordinary shares

**(b) Name of Issuer:**
Illumination Acquisition Corp. I

**(c) Address of Issuer's Principal Executive Offices:**
570 LEXINGTON AVENUE, 40TH FLOOR, NEW YORK, NY, 10022

**Item 4. Purpose of Transaction**

November 21, 2025, Sponsor, as sponsor of the Issuer, acquired an aggregate of7,666,667 ordinary shares for an aggregate purchase price of $25,000, or approximately $0.003 per share. On February 26, 2026, the Issuer consummated its initial public offering ("IPO") and in connection with the consummation, the Sponsor purchased an aggregate of 365,000 units for an aggregate purchase price of $3,650,000. Each unit purchased was comprised of one Class A ordinary share of the Issuer and one-third of one redeemable warrant of the Issuer, with each whole warrant exercisable to purchase one Class A ordinary share upon consummation of an initial business combination.

The reporting persons made the acquisitions reported in this Schedule 13D as sponsor, officers and directors of the Issuer and in support of the Issuer's business plan. The reporting persons may acquire or dispose of additional securities or sell securities of the Issuer from time to time in the market or in private transactions, including as a result of ownership of the warrants referred to above. However, reporting persons do not have any other agreements to acquire additional Class A ordinary shares at this time.

As officers and directors of the Issuer, Lipman and Rosenberg are involved in making material business decisions regarding the Issuer's policies and practices and may be involved in the consideration of various proposals considered by the Issuer's board of directors. Additionally, as the Issuer's business plan is to enter into a business combination, Lipman and Rosenberg, as officers and directors of the Issuer, are actively involved in pursuing a suitable target for the Issuer's business combination and will be actively involved in effecting any such business combination if the Issuer's business plan is successful, which may also result in a change in the Issuer's board of directors, corporate structure or charter.

As of the date of this Schedule 13D, except as set forth in this Schedule 13D above, the reporting persons do not have any plans or proposals which would result in:

(a)( A ) The acquisition by any person of additional securities of the issuer, or the disposition of securities of the issuer;
(b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the issuer or any of its subsidiaries;
(c) A sale or transfer of a material amount of assets of the issuer or any of its subsidiaries;
(d) Any change in the present board of directors or management of the issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board;
(e) Any material change in the present capitalization or dividend policy of the issuer;
(f) Any other material change in the issuer's business or corporate structure, including but not limited to, if the issuer is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by section 13 of the Investment Company Act of 1940;
(g) Changes in the issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the issuer by any person;
(h) causing a class of securities of the issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association;
(i) A class of equity securities of the issuer becoming eligible for termination of registration pursuant to section 12(g)(4) of the Act; or
(j) Any action similar to any of those enumerated above.

The holders of a majority of these securities are entitled to make up to three demands that the Issuer register such securities. In additional, the holders have certain piggy-back registration rights with respect to registration statements filed subsequent to consummation of the Issuer's Business Combination. The Issuer will bear the expenses incurred in connection with the filing of any such registration statements.

Pursuant to the Insider Letter Agreement, Sponsor, Lipman and Rosenberg agreed, among other things, to vote all Class A ordinary shares owned by them, subject to applicable securities laws, in favor of a proposed Business Combination, not to sell or transfer any securities of the Issuer, subject to certain exceptions, until certain periods of time set forth in the Insider Letter Agreement and that they would not seek redemption rights with respect to any Class A ordinary shares held by them.
